• Fiber reinforced plastics with some fibers parallel to the loading direction could be considered an elastic body which is subject to cumulative failure because the residual strain was relatively small. The tensile stress and strain relations of such materials were analyzed by using a stochastic cumulative failure model with Strong Part and Weak Part. Their failure processes were one-step stochastic processes and the transition probabilities were expressed as a simple function of the stress applied to each Part. The constitutive equation of this failure model is very simple and the culculated results show a good agreement with the experimental results.
