A combined discrete element method (DEM) and finite element method (FEM) is presented. A 2D program is developing for application to mesoscale simulation of heterogeneous and homogeneous material under shock loading, and the numerical simulations are testified. The results of simulation are in agreement with those of theory, which verifies that the combined method is viable.

阐述了一种离散元与有限元法相结合的计算方法,编制了可应用于细观模拟的二维程序,对受冲击载荷作用的均匀材料和非均匀材料的响应特征进行了计算,并对数值模拟进行了验证。计算结果与理论值较吻合,验证了方法的可行性。

有限元  /  离散元  /  细观模拟  /  计算方法

A combined discrete element method (DEM) and finite element method (FEM) is presented. A 2D program is developing for application to mesoscale simulation of heterogeneous and homogeneous material under shock loading, and the numerical simulations are testified. The results of simulation are in agreement with those of theory, which verifies that the combined method is viable.
