Abstract

Method of calculation and experimental estimation of crack growth resistance under cyclic elastoplastic deformation is proposed. This method is based on measuring of local plastic strain near the crack tip and plotting the cyclic elasto-plastic fracture diagram for a specimen with a crack. Analysis of two types of the cyclic elasto-plastic fracture diagrams and their parameters is made. Ex-perimental D-diagrams of cyclic elasto-plastic fracture for the plastic carbon steel are given.
