An algorithm for the reliability calculating of stochastically defective orthotropic composite materials under conditions of a complex stress state is described. The criterion of maximum macroscopic stresses for a composite with arbitrarily oriented cracks with a predominant orientation in the direction of reinforcement is considered. The distribution function of the composite failure loading is obtained. The calculation is carried out and diagrams are constructed for the dependence of the test material sample probability of fracture on the applied loading for different number of cracks and structural heterogeneityRéférences
