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.
