New Plastic Crack-Tip Opening Displacement Tool Based on Digital Image Correlation for Estimating the Fatigue-Crack-Growth Law on 316L Stainless Steel

This work presents a new approach for studying crack growth resulting from fatigue, which utilizes the plastic contribution of crack-tip opening displacement (CTOD ). CTOD is used to predict austenitic stainless-steel crack propagation. Unlike linear elastic fracture mechanics analysis, the method p...
