Abstract: A mixed-mode delamination of laminate plate made of two sublaminates is presented in the paper. An opening and sliding load mode is obtained as failure model. A quasistatic rate-independent delamination problem of laminate plate with a finite thickness is proposed. A rate-independent delamination model for a laminate Kirchhoff-Love plate is considered as limit of quasistatic process. The failure model is implemented in FEM code to calculate the mixed-mode delamination response. The analysis is based on interface techniques. Within the interface finite element modeling there are calculated the individual components of damage parameters as spring reaction forces, relative displacements and energy release rates along the delamination front.

Keywords: Delamination, laminate plate, opening and sliding load mode, mixed response mode
