摘要
Abstract
A finite element model of composite laminates with delaminations was established by using a commercial finite-element software.The damage of elements was judged with Hashin failure criteria,and the stiffness reduction was carried out by UMAT subroutine.The interlaminar properties were simulated using cohesive elements,and the elements of delamination area were weakened.The initial and evolution of interlaminar damage was judged by stress failure criterion and energy release criterion.Compression test were carried out on unidirectional laminate specimens with and without delaminations.The effects of the position and size of delamination on compressive properties of the material were obtained.Good agreement was obtained between finite-element predictions and experimental results.关键词
