Evaluation of the matrix cracking formation in a cross-ply composite laminate under uniform tension load

One of the important issues about the composite materials indifferent loading conditions is the onset and propagation ofmatrix cracking damage mode, which affects thefunctionality of these materials significantly. In the presentstudy a novel computational method is proposed forpredicting the initiation and propagation of small 2-D crackswhich finally will cause the fracture in 90° layer in a[0/90/0] composite laminate. By exerting a uni-axial loadingto a cross ply composite laminate in which the 90° laminaconsists of different random representative volume elements(RVE’s), the possibility of microcarcking initiation andmatrix cracking formation will be examined. To this end, thebenefits of cohesive zone model via cohesive surfacemethod is applied.
