Theoretical and numerical validations are performed for the ABAQUS contour integral J C(t) functions in its versions v6.11-14 cases with residual stresses. Test specially designed to introduce various stress types followed by cracked-body fracture/creep analyses. Crack driving force parameters evaluated using both inbuilt v6.14 self-developed software. Based on results, guidance is developed users obtain correct values v6.11-14.
