摘要
本文应用弹性力学理论对Cundall的离散元模型进行了改进,提出线性变刚度和非线性常刚度两种模型,然后利用改进后的离散无法对颗粒介质变形及其力学过程进行了计算与分析,得到了较为满意的计算结果。
The improvement of the Cundall's discrete element model is made on the basis of elasticity theory and is reported in this paper. Two constitutive models with linearly-varying stiffness and constant non-linear stiffness are proposed. The improved discrete element method is used in the calculation and analysis of the deformation and mechanical processes of granular media and satisfactory results are obtained.
