Description : Bomb rack link
Problem : PH 13-8 Mo (H950) Link failed during low temperature (-70 F) testing
Analysis : Damage accumulation due to bending of under-designed component
propagated a brittle failure
Resolution & Recommendations :
Increase link cross section by 50% to decrease the net-section
stresses or replacing 13-8 Mo with a Ni-base Superalloy for superior cryogenic properties.
