摘要
Abstract
Considering the random distribution of fibers and voids,the representative volume element (RVE) of the composites microstmcture with random voids is generated by random algorithm.Then,by creating finite element model of RVEs and considering the elasticity-plasticity of matrix and bilinear traction-separation law for interface,the effect of void contents on transverse behavior of unidirectional composites is simulated by the finite element analysis.It is found that the effect of random distribution of voids is small on transverse properties.When void content is less than critical value,the influence of voids on transverse properties is weak relatively.When void content is more than critical value,the reduction in transverse modulus,transverse tension strength and transverse compression strength becomes signiticant.关键词
