| 1 | WAVELET METHOD FOR CALCULATING THE DEFECT STATES OF TWO-DIMENSIONAL PHONONIC CRYSTALS显示文摘Based on the variational theory,a wavelet-based numerical method is developed to calculate the defect states of acoustic waves in two-dimensional phononic crystals with point and line defects.The supercell technique is applied.By expanding the displacement field and the material constants (mass density and elastic stiffness) in periodic wavelets,the explicit formula- tions of an eigenvalue problem for the plane harmonic bulk waves in such a phononic structure are derived.The point and line defect states in solid-liquid and solid-solid systems are calcu- lated.Comparisons of the present results with those measured experimentally or those from the plane wave expansion method show that the present method can yield accurate results with faster convergence and less computing time. | Zhizhong Yah Yuesheng Wang Chuanzeng Zhang | 2008 | Acta Mechanica Solida Sinica2008，21，2： | 16 |
| 2 | On carbonation behavior of recycled aggregate concrete显示文摘This study tries to reveal the carbonation behavior when recycled coarse aggregates(RCAs) are used to mix new concrete.Six series of tests including 22 groups of recycled aggregate concrete(RAC) specimens were carried out,in which the effects of the water/binder(w/b) ratios,the binder content,the types of mineral admixture,the quality of RCAs,the RCAs replacement and the loading levels on the carbonation behavior of RAC were evaluated,respectively.The results showed that the carbonation behavior of RAC was not only influenced by the quality of new mortar but also by the properties of RCAs.The admixture of mineral admixture influenced the carbonation,and the loading stress level might have a significant impact on the evolution of the carbonation. | XIAO JianZhuang LEI Bin ZHANG ChuanZeng | 2012 | Science China(Technological Sciences)2012，55，9： | 7 |

| 4 | 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 |
| 5 | Band structures of transverse waves in nanoscale multilayered phononic crystals with nonlocal interface imperfections by using the radial basis function method显示文摘A radial basis function collocation method based on the nonlocal elastic continuum theory is developed to compute the band structures of nanoscale multilayered phononic crystals. The effects of nonlocal imperfect interfaces on band structures of transverse waves propagating obliquely or vertically in the system are studied. The correctness of the present method is verified by comparing the numerical results with those obtained by applying the transfer matrix method in the case of nonlocal perfect interface. Furthermore, the influences of the nanoscale size, the impedance ratio and the incident angle on the cut-off frequency and band structures are investigated and discussed in detail. Numerical results show that the nonlocal interface imperfections have significant effects on the band structures in the macroscopic and microscopic scale. | Zhizhong Yan Chunqiu Wei Chuanzeng Zhang | 2017 | Acta Mechanica Sinica2017，33，2： | 2 |
| 6 | ELASTIC SH WAVE PROPAGATION IN PERIODIC LAYERED COMPOSITES WITH A PERIODIC ARRAY OF INTERFACE CRACKS显示文摘The interaction of anti-plane elastic SH waves with a periodic array of interface cracks in a multi-layered periodic medium is analyzed in this paper. A perfect periodic structure without interface cracks is first studied and the transmission displacement coefficient is obtained based on the transfer matrix method in conjunction with the Bloch-Floquet theorem. This is then generalized to a single and periodic distribution of cracks at the center interface and the result is compared with that of perfect periodic cases without interface cracks. The dependence of the transmission displacement coefficient on the frequency of the incident wave, the influences of material combination, crack configuration and incident angle are discussed in detail. Compared with the corresponding perfect periodic structure without interface cracks, a new phenomenon is found in the periodic layered system with a single and periodic array of interface cracks. | Zhizhong Yan Chunqiu Wei Chuanzeng Zhang | 2015 | Acta Mechanica Solida Sinica2015，28，5： | 2 |
| 7 | MODIFIED SZABO'S WAVE EQUATION FOR ARBITRARILY FREQUENCY-DEPENDENT VISCOUS DISSIPATION IN SOFT MATTER WITH APPLICATIONS TO 3D ULTRASONIC IMAGING显示文摘Soft matters are observed anomalous viscosity behaviors often characterized by a power law frequency-dependent attenuation in acoustic wave propagation.Recent decades have witnessed a fast growing research on developing various models for such anomalous viscosity behaviors,among which one of the present authors proposed the modified Szabo's wave equation via the positive fractional derivative.The purpose of this study is to apply the modified Szabo's wave equation to simulate a recent ultrasonic imaging technique called the clinical amplitudevelocity reconstruction imaging(CARI) of breast tumors which are of typical soft tissue matters.Investigations have been made on the effects of the size and position of tumors on the quality of ultrasonic medical imaging.It is observed from numerical results that the sound pressure along the reflecting line,which indicates the detection results,varies obviously with sizes and lateral positions of tumors,but remains almost the same for different axial positions. | Xiaodi Zhang Wen Chen Chuanzeng Zhang | 2012 | Acta Mechanica Solida Sinica2012，25，5： | 2 |
| 8 | ANALYSIS OF A CRACK IN A FUNCTIONALLY GRADED STRIP WITH A POWER FORM SHEAR MODULUS显示文摘The plane strain problem of a crack in a functionally graded strip with a power form shear modulus is studied.The governing equation in terms of Airy’s stress function is solved exactly by means of Fourier transform.The mixed boundary problem is then reduced to a system of singular integral equations and is solved numerically to obtain the stress intensity factor at crack-tip.The maximum circumferential stress criterion and the strain energy density criterion are both employed to predict the direction of crack initiation.Numerical examples are given to show the influence of the material gradation models and the crack sizes on the mode-I and mode-II stress intensity factors.The dependence of the critical kink-angle on the crack size is examined and it is found that the crack kink-angle decreases with the increase of the normalized crack length, indicating that a longer crack tends to follow the original crack-line while it is much easier for a shorter crack to deviate from the original crack-line. | Jinju Ma Zheng Zhong Chuanzeng Zhang | 2009 | Acta Mechanica Solida Sinica2009，22，5： | 2 |
| 9 | 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 |
| 10 | RBF collocation method and stability analysis for phononic crystals显示文摘The mesh-free radial basis function(RBF) collocation method is explored to calculate band structures of periodic composite structures. The inverse multi-quadric(MQ), Gaussian, and MQ RBFs are used to test the stability of the RBF collocation method in periodic structures. Much useful information is obtained. Due to the merits of the RBF collocation method, the general form in this paper can easily be applied in the high dimensional problems analysis. The stability is fully discussed with different RBFs.The choice of the shape parameter and the effects of the knot number are presented. | Chunqiu WEI Zhizhong YAN Hui ZHENG Chuanzeng ZHANG | 2016 | Applied Mathematics and Mechanics(English Edition)2016，37，5： | 1 |
