Abstract:

A double-box test was devised to compare the effects of internal and external cyclic pressurization on the low-cycle fatigue behavior of HY-80 steel. The outer box was fabricated from 2-inch-thick plate and the inner box from 1-inch-thick plate. Major conclusions reached from this and previous tests were 1 the fatigue life of an externally pressurized box is appreciably greater than that of an internally pressurized box and 2 the fatigue crack propagation rate of an internally pressurized box having a 1-inch wall thickness is more than five times higher than that of one having a 1-inch wall thickness.
