摘要：

In this article, the finite element method (FEM) using cohesive element is applied to predict the delamination buckling and growth in slender laminated composite with embedded delamination under compressive load. In particular, the study is focused on the significant effects of delamination buckling for various parameters in slender composite laminate, such as model length-width ratio, delamination shape, delamination size, and delamination depth position. Furthermore, the delamination growth is assessed to investigate the influence of some key parameters (delamination size and delamination depth position) on the delamination growth load, growth shape and direction.
