Crack Growth in Ni-Cr-Mo-V Steel Using ΔCTOD Elastic–Plastic Model

open access: yesJournal of Marine Science and Engineering, 2022
Many studies have shown that the linear elastic fracture mechanics (LEFM) method based on the stress intensity factor range (ΔK) has limitations that cannot be ignored. Due to neglecting the influence of plastic deformation near the crack tip, LEFM shows
