 Crack growth resistance curve

A Crack Growth Resistance Curve, often referred to as a J-R curve (J-Resistance Curve), is a graphical representation used in materials science and fracture mechanics to illustrate the relationship between crack growth resistance and stable crack extension in materials, particularly in ductile materials. ### Key Components: 1. **J-Integral**: This is a measure of the energy release rate or driving force for crack growth. It is a path-independent integral used to characterize the stress and strain field near the crack tip.
