Laser-Heating-Induced Failure of Metal Alloys Under Constant Stress



The failure conditions of three structural materials have been investigated under a number of constant axial tensile stresses and rapid heating rates. Laser heating was used to produce failure by fracture for selected times between nominally 0.10 and 100 s. The three sheet gage materials tested were 2024-T81 (alclad), Ti-6Al-4V (mill annealed), and 301 stainless steel (hard). Properties determined in this manner are applicable to vulnerability analyses of aircraft and missile structures. Temperatures for 1-s failure times of constantly stressed parts are significantly higher than those which accompany both the static ultimate tensile strength and long-duration creep rupture behaviors.
