Delamination of Laminate Plates

摘要

The paper deals with numerical modeling of delamination of laminate plate consists of unidirectional fiber reinforced layers. The methodology adopts the first-order shear laminate plate theory and fracture and contact mechanics. There are described sublaminate modeling and delamination modeling by the help of finite element (FE) analysis. With the interface modeling there is calculated the energy release rate along the delamination front. Numerical results are given for mixed mode delamination problems by implementing the finite element method in a 2D analysis, which utilizes shear deformable plate elements and interface elements. Numerical example is done by the commercial FE software ANSYS.
