Abstract

This study presents the peridynamic simulation of laminated composites with defects such as delamination and fiber waviness. As part of the peridynamic simulations, an energy based critical stretch parameter is proposed to invoke the effects of different deformation/loading modes. Peridynamic simulations of delamination growth in Double Cantilever Beam (DCB) specimen and laminate with wavy fibers under compression provide both damage initiation and progression. These predictions are compared with numerical and experimental results available in literature; they show remarkable agreement.
