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

KEYWORDS
