%X 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.
