Mixed-Mode Delamination Failure Model of Sandwich Plate

Abstract

-Plane fracture of two plies is defined as delamination that can be found between plies in a laminate or sandwich structure. The interface model is solved using fracture and contact mechanics. Within the standard First-Order Deformation Theory of laminates, the mixed-mode delamination failure model is solved. The damage propagation parameters are calculated using the ANSYS code. The delamination problem is solved in a numerical example.
