摘要
由变形体动力学原理和模态分解法,推导出可变形块体单元模型,并根据离散元法的基本原理,选择合理接触模型,依照动态松弛法,编制相应的计算程序.由静力问题为例,验证了离散元应用于可变形体的可行性.
In this paper, the discrete element model for deformable bodies is deduced according to the principle of dynamics for deformable bodies and model decomposition.The proper contact model is selected according to the fundamental principle of discrete element method. With the dynamic relaxation method, the corresponding calculating program is worked out. An example for a static problem is presented to test the validity of the discrete element method applied to deformable dodies.
