Post-buckling delamination propagation analysis using interface element with de-cohesive constitutive law

摘要

In this paper, the cohesive zone constitutive law is implemented at interface between delaminated layers to simulate buckling driven delamination propagation in the laminates. The influence of single and multi delaminations on postbuckling behaviour of laminated are investigated and compared by obtained results of other method and the available experiments. It is shown that post-buckling delamination propagation can be predicted well, by utilizing a damageable interface element.
