Computer modeling of compression for large cell spatially reinforced composite specimen enclosed in the ring for elimination of edge effects influence

Abstract

Article is dedicated to numerical simulation of compression test of the prismatic specimen of the spatially reinforced composite material in which the mechanisms leading to collapse of basic surfaces are weakened. It is shown that areas of the maximum stresses settle down in a working part of the specimen, initiating macrodestruction by a cut. The structural-phenomenological approach is applied to the description of deformation and fracture of the specimen.
