Title:Cyclic stress behavior of a 286 alloy for conditions of controlled strain
Author(s):Ross, A.S.; Morrow, JoDean
Subject(s):Cyclic Stress
Controlled Strain
Abstract:When an axial fatigue specimen is subjected to repeated strain cycling about a fixed mean strain value, the average or mean stress decreases with the number of strain cycles. This cycle-dependent stress relaxation is analogous to the relaxation or decay of macro-residual stresses in a member subjected to fatigue loading. To explore this type of material behavior nearly 50 tubular fatigue specimens of A-286 alloy steel have been axially tested under conditions of controlled strain, and the cycle-dependent relaxation of mean stress measured. Fatigue data for initial means stresses are also reported. It was found that in the case of A-286 alloy most of the relaxation occurred early in the fatigue life, especially during the first ten cycles. In this respect the cyclic behavior of A-286 was found to be substantially different from that of SAE 4340 which was investigated earlier by Morrow and Sinclair.
