Abstract

A probabilistic model utilizing random material characteristics to predict damage evolution in textile laminates is presented. The model is based on a division of each ply into two sublaminas consisting of cells. The probability of cell failure is calculated using stochastic function theory and the maximal strain failure criterion. Three modes of failure, i.e., fibre breakage, matrix failure in the transverse direction, as well as matrix or interface shear cracking are taken into account. Computed failure probabilities are utilized in reducing cell stiffness based on the mesovolume concept. A numerical algorithm is developed predicting the damage evolution and deformation history of textile laminates. The effect of scatter of fibre orientation on cell properties is discussed. Weave influence on damage accumulation is illustrated using a Kevlar/epoxy laminate.
