Abstract

The aim of this paper is to evaluate the effective properties of composite materials with periodic random packing of ellipsoids of different volume fractions and aspect ratios. Therefore, we employ computational homogenization. A very efficient MD-based method is applied to generate the periodic random packing of the ellipsoids. The method is applicable even for extremely high volume fractions up to 60%. The influences of the volume fraction and aspect ratio on the effective properties of the composite materials are studied in several numerical examples.

摘要

本文的目的是评估具有不同体积分数和纵横比的椭球体周期性随机堆积的复合材料的有效性能。因此，我们采用计算均匀化方法。一种基于分子动力学的高效方法被用于生成椭球体的周期性随机堆积。该方法甚至适用于高达60%的极高体积分数。通过几个数值例子研究了体积分数和纵横比对复合材料有效性能的影响。
