| 1 | EXTENSION OF COMBINED SELF-CONSISTENT AND MORI-TANAKA APPROACH TO EVALUATION OF ELASTOPLASTIC PROPERTY OF PARTICULATE COMPOSITES显示文摘The combined self-consistent and Mori-Tanaka approach proposed for the evaluation of the effective elastic property of particulate composites is extended to evaluate the effective elastoplastic property of particulate composites.Suppose there are sufficient identical particle inclusions with total volume fraction c in a representative volume element(RVE)of a particulate composite,these inclusions are separated into two groups,with volume fractions(1-λ-1)c and c/λ over the RVE,respectively.We assume that the first group of inclusions has already been embedded in the original matrix to form a fictitious matrix,and the RVE of the composite consists of the fictitious matrix and the second group of particle inclusions.The property of the fictitious matrix is determined by the conventional self-consistent scheme,while the effective elastoplastic property of the composite is determined by the conventional Mori-Tanaka scheme.Analysis shows that,the conventional Mori-Tanaka scheme and self-consistent scheme can be obtained as the two limit cases of the extended approach as λ = 1 and λ = ∞,respectively.The constitutive behavior of the inclusions in either Group I or Group II is identical,indicating the consistency in the description of the constitutive behavior in the two steps.Furthermore,the effective elastoplastic behavior of some typical particulate composites is analyzed,and the satisfactory agreement between the computational and experimental results demonstrates the validity of the extended approach.The introduced λ can serve reasonably as a parameter,which is related to the actual property of composites and can be identified by experiments,for a more accurate evaluation of the effective elastoplastic property of particulate composites. | Xianghe Peng Ning Hu Xuesong Long Hengwei Zheng | 2013 | Acta Mechanica Solida Sinica2013，26，1： | 5 |
| 2 | MICROMECHANICAL DAMAGE MODEL FOR ROCKS AND CONCRETES SUBJECTED TO COUPLED TENSILE AND SHEAR STRESSES显示文摘Based on the analysis of the deformation in an infinite isotropic elastic matrix with an embedded elliptic crack under far field coupled tensile and shear stresses, the energy release rate and a mixed fracture criterion are obtained using an energy balance approach. The additional compliance tensor induced by a single opening elliptic microcrack in a representative volume element is derived, and the effect of microcracks with random orientations is analyzed with the Taylor’s scheme by introducing an appropriate probability density function. A micromechanical damage model for rocks and concretes is obtained and is verified with experimental results. | Zhongjun Ren Xianghe Peng Chunhe Yang | 2008 | Acta Mechanica Solida Sinica2008，21，3： | 4 |
| 3 | A CONSTITUTIVE MODEL FOR TRANSFORMATION, REORIENTATION AND PLASTIC DEFORMATION OF SHAPE MEMORY ALLOYS显示文摘A constitutive model is developed for the transformation, reorientation and plastic deformation of shape memory alloys (SMAs). It is based on the concept that an SMA is a mixture composed of austenite and martensite, the volume fraction of each phase is transformable with the change of applied thermal-mechanical loading, and the constitutive behavior of the SMA is the combination of the individual behavior of its two phases. The deformation of the martensite is separated into elastic, thermal, reorientation and plastic parts, and that of the austenite is separated into elastic, thermal and plastic parts. Making use of the Tanaka's transformation rule modified by taking into account the effect of plastic deformation, the constitutive model of the SMA is obtained. The ferroelasticity, pseudoelasticity and shape memory effect of SMA Au-47.5 at.%Cd, and the pseudoelasticity and shape memory effect as well as plastic deformation and its effect of an NiTi SMA, are analyzed and compared with experimental results. | Xianghe Peng Bin Chen Xiang Chen Jun Wang Huyi Wang | 2012 | Acta Mechanica Solida Sinica2012，25，3： | 3 |

| 15 | Anisotropic and asymmetric deformation mechanisms of nanolaminated graphene/Cu composites显示文摘We conducted molecular dynamics (MD) simulations of tension and compression along the <112> direction and MD simulations of compression along the <110> and <111> directions on nanolaminated graphene/Cu (NGCu) composites to investigate the effects of the incorporated graphene and the deformation mechanisms related to the loading direction. The deformation behavior and the defect structures were found to be strongly dependent on the loading conditions. An asymmetric tension-compression deformation behavior was thus found in graphene/Cu nanolaminates under the <112> loading, which was dominated by stacking faults and deformation twins formed by dislocation slide under tension and compression, respectively. High density and ordered nanotwins were formed at the graphene/Cu interfaces. Two different formation mechanisms of the twins were found under the <112> compression, and the nucleated twins were easy to be thickened with the assistance of the graphene wrinkles. Multiple twins were formed under the <110> compression by the dislocation cross-slip. This study provides a way to introduce graphene reinforcement and twin boundary to Cu matrix composites and design nanotwinned graphene/Cu composites with excellent mechanical performance. | Shayuan Weng Huiming Ning Tao Fu Ning Hu Shu Wang Kaiyan Huang Xianghe Peng H.
