Abstract

A multiscale approach called Multiscale Projection Method is adapted for the analysis of fiber microbuckling (fiber kinking) in laminated composites. Based on this global/local multiscale scheme, in the parts of the 0 degree layers of the laminate, where the fiber microbuckling is expected to happen, a fine scale mesh, with the geometrical details and material property of the fiber and matrix, is projected and a concurrent multiscale solution is sought to capture the kink band formation. The delamination between the buckled 0 degree layer and its neighboring plies is simulated using geometrically nonlinear cohesive elements. The effectivity of the proposed multiscale method is investigated through a numerical study of the fiber microbuckling in a 90:2/0/90_2 composite laminate.
