滑石破碎过程数值模拟的对比

Contrasts of Numerical Simulation's about Talc Crushing Process

为深入研究滑石块体受冲击时的具体破碎过程,分别利用MCA2D和ABAQUS模拟软件进行模拟,对结果进行对比分析。结果表明,利用MCA2D软件可以在一定条件下模拟单颗粒材料破碎过程;可以用静载实验的应力应变曲线去模拟冲击过程;试件接触的边角位置首先产生缺陷而导致破碎。

The paper carries on the simulation using MCA 2D and the ABAQUS simulation software for deeply research talc crushing process under impact. The result indicated after contrasts it＇s possible uses MCA 2D software to simulate the single granular materials crushing process under the controlled condition; May use the dead load experiment＇s stress to simulate the impact process; the flaw first produces in the test sample contact comer position, and causes crashing.
