Abstract

The paper deals with identifying of the damage model for a bundle of T300 and AS4D fibers under tensile load. The damage model is implemented in ANSYS for a one-dimensional bar element and obtained the strain-stress response of a bundle of fibers. The delamination of laminate plate, which consists of unidirectional fiber reinforced layers, is investigated. The methodology adopts the first-order shear laminate plate theory and fracture and contact mechanics. Within the interface modeling there are calculated the individual components of energy release rate along the lamination front. Numerical results are given for mixed mode delamination problems. Numerical example is done by the commercial ANSYS code.
