Cleavage Fracture Quantified by J and A

Source

The analytical asymptotic solutions including higher order terms for stresses at a crack tip embedded in a power law elastic-plastic material are applied to the interpretation of cleavage fracture for a mild steel. It is demonstrated that fracture initiation can be determined by using two parameters J and A₂ — J represents the level of loading and A₂ quantifies the level of constraint. Constraint related issues such as size effect, transferability, and biaxial stress effect are investigated. The predicted results have the same trend as seen experimentally.
