Measurement of the strength for composite materials is very difficult because those failure processes imply various failure modes, which are, for example, an interlaminar delamination, a destruction of matrix and an interfacial fracture between a fiber and a matrix. However, that strength is the most important characteristic in structural design using composite materials. Hence we try a fractural progress analysis of composite materials using a quasi-3-dimensional analysis method under a tensile load. A quasi-3-dimensional model is constructed of shell elements and beam elements which represent fiber and matrix, respectively. The fractural progress analysis of the composite materials is carried out to evaluate this proposed model. The precision of the analysis is very good. Therefore we confirm that this proposed model can simulate a transverse crack an interlaminar fracture.
