Abstract

We have proposed a model of the deformation and fracture of an elastoplastic body with an elastic spheroidal inclusion. The problem has been reduced to the solution of an integro-differential equation, and its numeral solution has been obtained by the method of mechanical quadratures. Using the strain criterion of crack initiation in the neighborhood of an inclusion, we have established the main parameters affecting local fracture. The results of investigations are presented in the form of plots.
