本文介绍了在计算机程序中实现的算法的开发，该计算机程序用于模拟由椭圆形颗粒组成的理想化颗粒系统的性能。这项工作是数值模拟方法的延伸，这些方法已被作者和其他人成功应用于盘状或多边形颗粒的微观力学研究。椭圆形颗粒的模拟提供了探索颗粒形状对颗粒平面组装体的微观力学行为以及这些系统在宏观尺度上的应力应变行为的影响的可能性。模拟运行的典型结果说明了颗粒形状对平面系统宏观应力应变响应的重要性。
The paper presents the development of algorithms that have been implemented in a computer program used to simulate the performance of idealized granular systems composed of elliptical-shaped particles. The work is an extension of numerical simulation methods which have been successfully used in micromechanics research on disk-shaped or polygon-shaped particles by the authors and others. The simulation of elliptical-shaped particles offers the possibility to explore the influence of particle shape on the micromechanical behaviour of plane assemblies of particles and the stress-strain behaviour of these systems at the macro scale. Typical results of simulation runs are presented to illustrate the importance of particle shape on the macroscopic stress-strain response of plane systems.
