Comparative Analysis of Crack Growth Characteristics Based on Virtual Crack Closure Technique

Abstract:

The strain energy rate and the stress intensity factors in different crack growth stage were analyzed by virtual crack closure technique. The user subroutine is complied using Abaqus finite element software. The finite element model of crack growth was established by the Paris formula, then the fatigue crack growth process is simulated, the crack growth life is predicted. The method could be a powerful tool for engineers to study the fracture and fatigue problems in engineering structures.
