| 1 | New numerical algorithms in SUPER CE/SE and their applications in explosion mechanics显示文摘The new numerical algorithms in SUPER/CESE and their applications in explosion mechanics are studied. The researched al-gorithms and models include an improved CE/SE (space-time Conservation Element and Solution Element) method,a local hybrid particle level set method,three chemical reaction models and a two-fluid model. Problems of shock wave reflection over wedges,explosive welding,cellular structure of gaseous detonations and two-phase detonations in the gas-droplet system are simulated by using the above-mentioned algorithms and models. The numerical results reveal that the adopted algorithms have many advantages such as high numerical accuracy,wide application field and good compatibility. The numerical algo-rithms presented in this paper may be applied to the numerical research of explosion mechanics. | WANG Gang1,2,WANG JingTao1 & LIU KaiXin1,3 1 LTCS and College of Engineering,Peking University,Beijing 100871,China 2 LHD,Institute of Mechanics,Chinese Academy of Sciences,Beijing 100190,China 3 Center for Applied Physics and Technology,Peking University,Beijing 100871,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，2： | 6 |
| 2 | New discrete element models for elastoplastic problems显示文摘The discrete element method (DEM) has attractivefeatures for problems with severe damages, but lack oftheoretical basis for continua behavior especially for nonlinearbehavior has seriously restricted its application.The present study proposes a new approach to developingthe DEM as a general and robust technique for modeling theelastoplastic behavior of solid materials. New types of connectivelinks between elements are proposed, the inter-elementparameters are theoretically determined based onthe principle of energy equivalence and a yield criterion anda flow rule for DEM are given for describing nonlinear behaviorof materials. Moreover, a numerical scheme, which canbe applied to modeling the behavior of a continuum as wellas the transformation from a continuum to a discontinuum,is obtained by introducing a fracture criterion and a contactmodel into the DEM. The elastoplastic stress wave propagationsand the tensile failure process of a steel plate aresimulated, and the numerical results agree well with thoseobtained from the finite element method (FEM) and correspondingexperiment, and thus the accuracy and efficiencyof the DEM scheme are demonstrated. | Ming Cheng Weifu Liu Kaixin Liu LTCS and Department of Mechanics and Aerospace Engineering,College of Engineering, Peking University, 100871 Beijing, China | 2009 | Acta Mechanica Sinica2009，25，5： | 2 |
