The experimental method for the estimation of crack growth resistance of the
structure and machine elements under cyclic elasto-plastic straining based on local plastic
strain near the crack tip and assuming to receive the complex of the force and strain
characteristics of crack growth resistance for plastic steels, is suggested. The basic fracture
characteristics are obtained due to cyclic elasto-plastic fracture diagram as result of standard
crack growth resistance tests and the measuring of the local plastic strain near the crack tip
