Abstract: In order to evaluate a crack-like flaw, a two-parameter method (FAD: failure assessment diagram) will be widely adopted. Ainsworth studied the plastic interaction between primary and secondary stresses, and proposed the plasticity interaction factor on the FAD. As the plasticity interaction factors are intrinsically dependent on the Failure Assessment Curve (FAC), this paper reveals the plasticity interaction factors for several FACs.

Keywords: Failure assessment diagram, plasticity interaction factor, crack-like flaw
