| 1 | Analysis and Simulation of Evolution Induced Catastrophe显示文摘A model of evolution induced catastrophe(EIC)characterized by a nonlocal interaction is proposed.The general feature of the model is its two bias states:explosively catastrophic and globally stable,both consisting in a cascade of locally unstable states.A one-dimensional analysis reveals a transition region from globally stable to catastrophe.A two-dimensional simulation gives a thin fractal fracture profile similar to that observed and also a possible spectrum of fracture fractal.All these are different from percolation.Hence,the EIC model may represent a prototype of natural processes. | BAI Yilong XIA Mengfen KE Fujiu LU Chunsheng LING Zhong | 1993 | Chinese Physics Letters1993，10，3： | 5 |
| 2 | Comparison of shear banding in BMGs due to thermal-softening and free volume creation显示文摘This paper reports a comparative study of shear banding in BMGs resulting from thermal softening and free volume creation. Firstly,the effects of thermal softening and free volume creation on shear instability are discussed. It is known that ther-mal softening governs thermal shear banding,hence it is essentially energy related. However,compound free volume creation is the key factor to the other instability,though void-induced softening seems to be the counterpart of thermal softening. So,the driving force for shear instability owing to free volume creation is very dif-ferent from the thermally assisted one. In particular,long wave perturbations are always unstable owing to compound free volume creation. Therefore,the shear instability resulting from coupled compound free volume creation and thermal softening may start more like that due to free volume creation. Also,the compound free volume creation implies a specific and intrinsic characteristic growth time of shear instability. Finally,the mature shear band width is governed by the corre-sponding diffusions (thermal or void diffusion) within the band. As a rough guide,the dimensionless numbers: Thermal softening related number B,Deborah number (denoting the relation of instability growth rate owing to compound free volume and loading time) and Lewis number (denoting the competition of different diffusions) show us their relative importance of thermal softening and free volume creation in shear banding. All these results are of particular significance in understanding the mechanism of shear banding in bulk metallic glasses (BMGs). | LIU LongFei DAI LanHong BAI YiLong KE FuJiu | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，9： | 2 |

| 8 | SELF-ADAPTIVE MOLECULE/CLUSTER STATISTICAL THERMODYNAMICS METHOD FOR QUASI-STATIC DEFORMATION AT FINITE TEMPERATURE显示文摘Hybrid molecule/cluster statistical thermodynamics (HMCST) method is an efficient tool to simulate nano-scale systems under quasi-static loading at finite temperature.In this paper,a self-adaptive algorithm is developed for this method.Explicit refinement criterion based on the gradient of slip shear deformation and a switching criterion based on generalized Einstein approximation is proposed respectively.Results show that this self-adaptive method can accurately find clusters to be refined or transferred to molecules,and efficiently refine or transfer the clusters.Furthermore,compared with fully atomistic simulation,the high computational efficiency of the self-adaptive method appears very attractive. | Hao Tan Haiying Wang Mengfen Xia Fujiu Ke Yilong Bai | 2011 | Acta Mechanica Solida Sinica2011，24，1： | 1 |
