An Estimation of Crack Growth Life for the Tubes of Linear Part of the Oil Pipeline with the Longitudinal Semielliptical Crack after Long Time Operation
To determine the crack growth resistance of tubes made of ductile steel using of approaches of linear elastic fracture mechanics it is incorrectly due to non-compliance with the conditions of plane strain. One of the variants of solutions to the problem lies in the extrapolation formulas for linear...
