Abstract

Basing on the fracture mechanics concepts on crack initiation and propagation in structural materials, the calculational model for prediction of durability of two contacting workpieces, subjected to cyclic loading is formulated in this work. The step-by-step calcula- tion of the fatigue cracks propagation paths is one of the impor- tant elements of the model. It is based on the singular integral equations method of the elasticity theory contact problems for two dimensional bodies weakened by a system of curvilinear cracks as well as on their numerical solution by mechanical quadratures. The proposed path construction algorithm allows to take into ac- count stresses redistribution, caused both by crack propagation and possible mutual displ
