2025 A10 CX Dataset and Round Robin

Point of Contact(s): Bob Pilarczyk

Objective: The A-10 program is transitioning toward using residual stresses from cold expansion directly in damage tolerance analyses. A test program was developed to target and isolate the load history and residual stress effects for Cx holes. Fatigue tests include baseline non-Cx and Cx holes, constant amplitude and spectrum loading, and are complimented with residual stress measurements for each condition.
