摘要
本文运用多刚体系统动力学和微结构连续力学的理论方法，考虑了颗粒体的拓扑结构及颗粒体之间的局部非线性相互作用，通过引进恢复系数，导出了适合于大变形运动（包括平动与转动）情况下，颗粒体间的滑移和分离的客观弹塑性本构关系．
In this paper, taking the topo structure and local nonlinear interaction of interparticles into account and intruducing coefficient of restitution,an elastoplastic law with sliding and seperation of patricles under large deformation for granular material is derived based on mutiply rigid dynamics and micro-mechanics approach.
