| 2 | Crack nucleation and propagation simulation in brittle two-phase perforated/particulate composites by a phase field model显示文摘Fracture is a very common failure mode of the composite materials,which seriously affects the reliability and service-life of composite materials.Therefore,the study of the fracture behavior of the composite materials is of great significance and necessity,which demands an accurate and efficient numerical tool in general cases because of the complexity of the arising boundary-value or initial-boundary value problems.In this paper,a phase field model is adopted and applied for the numerical simulation of the crack nucleation and propagation in brittle linear elastic two-phase perforated/particulate composites under a quasi-static tensile loading.The phase field model can well describe the initiation,propagation and coalescence of the cracks without assuming the existence and the geometry of the initial cracks in advance.Its numerical implementation is realized within the framework of the finite element method(FEM).The accuracy and the efficiency of the present phase field model are verified by the available reference results in literature.In the numerical examples,we first study and discuss the influences of the hole/particle size on the crack propagation trajectory and the force-displacement curve.Then,the effects of the hole/particle shape on the crack initiation and propagation are investigated.Furthermore,numerical examples are presented and discussed to show the influences of the hole/particle location on the crack initiation and propagation characteristics.It will be demonstrated that the present phase field model is an efficient tool for the numerical simulation of the crack initiation and propagation problems in brittle two-phase composite materials,and the corresponding results may play an important role in predicting and preventing possible hazardous crack initiation and propagation in engineering applications. | Xingxue Lu Yuliang Hou Ying Tie Cheng Li Chuanzeng Zhang | 2020 | Acta Mechanica Sinica2020，36，2： | 5 |
| 3 | Screen efficiency comparisons of decision tree and neural network algorithms in machine learning assisted drug design显示文摘In view of huge search space in drug design, machine learning has become a powerful method to predict the affinity between small molecular drug and targeting protein with the development of artificial intelligence technology. However, various machine learning algorithms including massive different parameters make the prediction framework choice to be quite difficult. In this work, we took a recent drug design competition(from XtalPi company on the DataCastle platform) as the typical case to find the optimized parameters for different machines learning algorithms and the most effective algorithm. After the parameter optimizations, we compared the typical machine learning methods as decision tree(XGBoost, LightGBM) and artificial neural network(MLP, CNN) with root-mean-square error(RMSE) and coefficient of determination(R^2) evaluation. As a result, decision tree is more effective than the neural network as LightGBM>XGBoost>CNN>MLP in the affinity prediction of the specific drug design problem with ~160000 samples. For a much larger screening task in a more complicated drug design study, the sophisticated neural network model may go beyond the decision tree algorithm after generalization enhancing and overfitting reducing. The advanced machine learning methods could extract more information of protein-ligand bindings than traditional ones and improve the screen efficiency of drug design up to 200–1000 times. | Qiumei Pu Yinghao Li Hong Zhang Haodong Yao Bo Zhang Bingji Hou Lin Li Yuliang Zhao Lina Zhao | 2019 | Science China Chemistry2019，62，4： | 5 |

| 5 | A novel surrogate modeling strategy of the mechanical properties of 3D braided composites显示文摘In this paper,a surrogate-based modeling methodology is developed and presented to predict the elastic properties of three dimensional(3 D)four-directional braided composites.Using this approach,the prediction process becomes feasible with only a limited number of training points.The surrogate models constructed using Finite Element(FE)method and Diffuse Approximation,reduce the computational time and cost for preparing experimental samples.In the FE model,multiscale method is applied to couple the computations of elastic properties at microscale and mesoscale.Subsequently,a parametric study is performed to analyze the effects of the three design parameters on the elastic properties.Satisfactory results are obtained via the surrogatebased modeling predictions,which are compared with the experimental measurements.Moreover,the predictions obtained from surrogate models concur well with the FE predictions.This study orients a new direction for predicting the mechanical properties based on surrogate models which can effectively reduce the sample preparation cost and computational efforts. | Zeyi LIU Yuliang HOU Qiaoli ZHAO Cheng LI | 2020 | Chinese Journal of Aeronautics2020，33，10： | 2 |
| 6 | Crack propagation simulation in brittle elastic materials by a phase field method显示文摘To overcome the difficulties of re-meshing and tracking the crack-tip in other computational methods for crack propagation simulations,the phase field method based on the minimum energy principle is introduced by defining a continuous phase field variable(x)∈[0,1]to characterize discontinuous cracks in brittle materials.This method can well describe the crack initiation and propagation without assuming the shape,size and orientation of the initial crack in advance.In this paper,a phase field method based on Miehe's approach[Miehe et al.,Comp.Meth.App.Mech.Eng.(2010)]is applied to simulate different crack propagation problems in twodimensional(2D),isotropic and linear elastic materials.The numerical implementation of the phase field method is realized within the framework of the finite element method(FEM).The validity,accuracy and efficiency of the present method are verified by comparing the numerical results with other reference results in literature.Several numerical examples are presented to show the effects of the loading type(tension and shear),boundary conditions,and initial crack location and orientation on the crack propagation path and force-displacement curve.Furthermore,for a single edge-cracked bi-material specimen,the influences of the loading type and the crack location on the crack propagation trajectory and force-displacement curve are also investigated and discussed.It is demonstrated that the phase field method is an efficient tool for the numerical simulation of the crack propagation problems in brittle elastic materials,and the corresponding results may have an important relevance for predicting and preventing possible crack propagations in engineering applications. | Xingxue Lu Cheng Li Ying Tie Yuliang Hou Chuanzeng Zhang | 2019 | Theoretical & Applied Mechanics Letters2019，9，6： | 2 |
| 7 | Darbepoetin alfa injection versus epoetin alfa injection for treating anemia of Chinese hemodialysis patients with chronic kidney failure:A randomized,open-label,parallel-group,non-inferiority Phase III trail显示文摘Background:Erythropoietin is a glycoprotein that mainly regulates erythropoiesis.In patients with chronic renal failure with anemia,darbepoetin alfa can stimulate erythropoiesis,correct anemia,and maintain hemoglobin levels.This study was designed to demonstrate the efficacy and safety of darbepoetin alfa injections as being not inferior to epoetin alfa injections(Recombinant Human Erythropoietin injection,rHuEPO)when maintaining hemoglobin(Hb)levels within the target range(10.0-12.0 g/dL)for the treatment of renal anemia.Methods:Ninety-five patients were enrolled in this study from April 15,2013 to April 10,2014 at 25 sites.In this study,patients(n=95)aged 18-70 years were randomized into a once per week intravenous darbepoetin alfa group(n=56)and a twice or three times per week intravenous epoetin alfa group(n=39)for 28 weeks,who had anemia with hemoglobin levels between 6 g/dL and 10 g/dL due to chronic kidney disease(CKD)and were undergoing hemodialysis or hemofiltration with ESA-naive(erythropoiesis stimulating agent-naive).The primary efficacy profile was the mean Hb level(the non-inferiority margin was-1.0 g/dL,week 21-28);the secondary efficacy profiles were the Hb increase rate(week 0-4),the target Hb achievement cumulative rate and time,the change trends of the Hb levels,and the target Hb maintenance ratio.Adverse events(AEs)were observed and compared,and the efficacy and safety were analyzed between the two treatment groups.Additionally,the frequencies of dose adjustments between the darbepoetin alfa and epoetin alfa groups were compared during the treatment period.SAS?software version 9.2 was used to perform all statistical analyses.Descriptive statistics were used for all efficacy,safety,and demographic variable analyses,including for the primary efficacy indicators.Results:The mean Hb level was 11.3 g/dL in the darbepoetin alfa group and 10.7 g/dL in the epoetin alfa group,respectively;the difference of the lower limits of the 95%confidence intervals(CI)between the two groups was 0.1 g/dL(>-1.0 g/dL),and non-inferiority was proven;the Hb levels started to increase in the first four weeks at a similar increase rate;no obvious differences were observed between the groups in the target Hb achievement cumulative rates,and the Hb levels as well as the target Hb level maintenance rate changed over time.The incidence of AEs was 62.5%in the darbepoetin alfa group and 76.9%in the epoetin alfa group.All the adverse events observed in the study were those commonly associated with hemodialysis.Conclusion:Darbepoetin alfa intravenously once per week can effectively increase Hb levels and maintain the target Hb levels well,which makes it not inferior to epoetin alfa intravenously twice or three times per week.Darbepoetin alfa shows an efficacy and safety comparable to epoetin alfa for the treatment of renal anemia. | Nan Chen Changying Xing Jianying Niu Bicheng Liu Junzhou Fu Jiuyang Zhao Zhaohui Ni Mei Wang Wenhu Liu Jinghong Zhao Ling Zhong Xiongfei Wu Wenge Li Yuqing Chen Wei Shi Jianghua Chen Aiping Yin Ping Fu Rong Wang Gengru Jiang Fanfan Hou Guohua Ding Jing Chen Gang Xu Yuichiro Kondo Yuliang Su Changlin Mei | 2022 | Chronic Diseases and Translational Medicine2022，8，1： | 1 |
| 8 | A multifunctional electrolyte with highly-coordinated solvation structure-in-nonsolvent for rechargeable lithium batteries显示文摘Rechargeable lithium-based battery is hailed as next-generation high-energy-density battery systems.However, growth of lithium dendrites, shuttle effect of lithium polysulfides intermediates and unstable interphase of high-voltage intercalation-type cathodes largely prevent their practical deployment.Herein, to fully conquer the three challenges via one strategy, a novel electrolyte with highlycoordinated solvation structure-in-nonsolvent is designed. On account of the particular electrolyte structure, the shuttle effect is completely suppressed by quasi-solid conversion of S species in Li-S batteries,with a stable cycle performance even at lean electrolyte(5μL mg^(-1)). Simultaneously, in-situ-formed highly-fluorinated interphases can not only lower Li+diffusion barrier to ensure uniform nucleation of Li but also improve stability of NCM cathodes, which enable excellent capacity retention of Lik LiNi(0.5)Co(0.2)Mn(0.3)O2 batteries under conditions toward practical applications(high loading of 2.7 m Ah cm^(-2) and lean electrolyte of 5 m L Ah^(-1)). Besides, the electrolyte is also nonflammable. This electrolyte structure offers useful guidelines for the design of novel organic electrolytes for practical lithium-based batteries. | Hui Zhao Jjinlei Gu Yuliang Gao Qian Hou Zengying Ren Yaqin Qi Kun Zhang Chao Shen Jun Zhang Keyu Xie | 2020 | Journal of Energy Chemistry2020，29，12： | 1 |

| 10 | Experimental and numerical investigation of mechanical behavior of plain woven CFRP composites subjected to three-point bending显示文摘The mechanical behavior of plain woven Carbon Fiber-Reinforced Polymer(CFRP)composites under Three-Point Bending(TPB)is investigated via experimental and numerical approaches.Multiscale models,including microscale,mesoscale and macroscale models,have been developed to characterize the TPB strength and damages.Thereinto,Representative Volume Elements(RVEs)of the microscale and mesoscale structures are established to determine the effective properties of carbon-fiber yarn and CFRP composites,respectively.Aimed at accurately and efficiently predicting the TPB behavior,an Equivalent Cross-Ply Laminate(ECPL)cell is proposed to simplify the inherent woven architecture,and the effective properties of the subcell are computed using a local homogenization approach.The macroscale model of the TPB specimen is constructed by a topology structure of ECPL cells to predict the mechanical behavior.The TPB experiments have been performed to validate the multiscale models.Both the experimental and numerical results reveal that delamination mainly appears in the top and bottom interfaces of the CFRP laminates.And matrix cracking and delamination are identified as the significant damage modes during the TPB process.Finally,the quasi-static and dynamic behaviors of plain woven composites are discussed by comparing the results of Low-Velocity Impact(LVI)and TPB simulations. | Qiaoli ZHAO Yuliang HOU Weihan WANG Yutong LIU Cheng LI | 2023 | Chinese Journal of Aeronautics2023，36，7： | 0 |
| 11 | Multi-layered plate finite element models with node-dependent kinematics for smart structures with piezoelectric components显示文摘This article presents a type of plate Finite Element(FE)models with adaptive mathematical refinement capabilities for modeling laminated smart structures with piezoelectric layers or distributed patches.The p-version shape functions are used in combination with the higher-order Layer-Wise(LW)kinematics adopting hierarchical Legendre polynomials.Node-Dependent Kinematics(NDK)is employed to implement local LW models in the regions with piezoelectric components and simulate the global substrate structure with the Equivalent Single-Layer(ESL)approach.Through the proposed NDK FE models,the electro-mechanical behavior of smart structures can be predicted with high fidelity and numerical efficiency,and various patch configurations can be conveniently modeled through one set of mesh grids.Moreover,the effectiveness and efficiency of the NDK FE approach are assessed through numerical examples and its application is demonstrated. | Guohong LI Erasmo CARRERA Yuliang HOU Gennady M.KULIKOV | 2021 | Chinese Journal of Aeronautics2021，34，8： | 0 |
