Elastoplastic Fracture Mechanics Approach to the Crack Growth Rate Computation of Modified Pipe Steels

A mechanophysical model for crack growth kinetics computation on stress corrosion fracture of modified 06G2BA and 08KhMCHA pipe steels is adequately expressed through the plane stress-strain state dα / dt and dJ / dt ratios that are dependent on the strain crack tip rate. The crack growth accelerate...
