Simulations of creep crack growth in 316 stainless steel using a novel creep-damage model Academic Article uri icon


  • The paper provides an advanced creep model which gives reasonable descriptions of the effects of damage and stress state from micromechanics viewpoint. A modified creep ductility exhaustion approach is employed to calculate the creep damage. Based on the proposed creep-damage model, numerical analyses of creep crack growth are conducted with a failure simulation technique. The simulated results are compared favorably with available experimental data for compact tension and thumbnail crack specimens for 316 stainless steel tested at 600 C. The comparisons show the excellent capability of the proposed model in predicting the crack growth rate and progressive crack profiles. 2013 Elsevier Ltd.
