论文简介
Abstract The objective of this work is to numerically investigate the anisotropic compressive
behavior of porous materials with randomly distributed, arbitrarily shaped pores in various
directions. The relative pore volume fraction, the anisotropic aspect ratio and the pore
arrangement are taken into account. The direction and anisotropic aspect ratio
dependences of Young׳ s modulus and the initial yield stress are examined. Our results
indicate that the anisotropic aspect ratio has a significant effect on the elasto-plastic ...
