LOW-CYCLE FATIGUE BEHAVIOR OF A DOUBLE-BOX STRUCTURE.
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.
