Hj. Shi et G. Pluvinage, CYCLIC STRESS-STRAIN RESPONSE DURING ISOTHERMAL AND THERMOMECHANICAL FATIGUE, International journal of fatigue, 16(8), 1994, pp. 549-557
Isothermal high-temperature low-cycle fatigue and in-phase and out-of-
phase thermomechanical fatigue tests were carried out on 316L austenit
ic stainless steel specimens controlled by computer. A nonlinear kinem
atic hardening model with internal variables was used to simulate the
cyclic stress-strain behaviour of isothermal fatigue. This model was m
odified by considering thermal cyclic effects in order to describe the
cyclic stress-strain behaviour of thermomechanical fatigue (TMF) usin
g only isothermal fatigue data and the material performance data. A ve
ry good approximation of the hysteresis loops was obtained by comparin
g with experiments of both in-phase and out-of-phase cases. The thermo
mechanical fatigue behaviour described by isothermal fatigue data give
s the possibility of developing the TMF lifetime prediction technique.
