Structural-probabilistic approach to determining the durability for structures of brittle materials

A structural-probabilistic model of fatigue failure of structures made of elasto-brittle materials and undergoing cyclic loading is proposed. The model is based on the use of the Daniels model of accumulation of defects in the form of flat stochastically dispersed microcracks and of the statistical strength criterion for materials whose failure occurs by forming rupture macrocracks. This statistical criterion is convenient to use in the study of...
