Life Analysis Development and Verification. Delivery Order 0012: Damage Tolerance Application of Multiple Through Cracks in Plates With and Without Holes

Abstract

This report documents the details of new stress intensity solutions for two independent through-the-thickness cracks in plates with and without holes. The solutions include both curve fits to detailed finite element models, and in some cases, used table lookup solutions for more complex cases. The solutions include the following: Two internal through cracks; Edge crack and an internal crack in a plate; Unequal edge cracks in a plate with unconstrained bending; Unequal edge cracks in a plate with constrained bending; Unequal through cracks at a hole; Through crack growing toward a hole; and Edge crack growing toward a hole.
