Effect of creep-fatigue loading condition on crack tip fields of grade 91 steel at crack initiation and growth

Published: Jul 27, 2021
Abstract
In this paper, the effect of creep-fatigue loading condition on crack tip deformation and stress fields of Grade 91 steel at 600 °C at crack initiation and growth is studied. By using finite element debond analysis method, creep-fatigue crack growth tests using C(T) specimens under various load ratios and hold times are simulated, and the effect of creep-fatigue load ratio and hold time on the crack opening profile, equivalent stress,...
