Аннотация

An algorithm for the reliability (probability of failure) calculating of composite materials with stochastically distributed dispersive inclusions under conditions of a complex stress state is proposed. The deterministic composite failure criterion of a Coulomb friction with clutch type is considered. The distribution function of the composite failure loading is obtained, which is the basis for writing the statistical characteristics of materials strength and reliability. The diagrams of the applied loading dependence on the probability of failure of a flat composite sample with different structural heterogeneity of the material and numbers of inclusions are calculated and constructed
