Abstract The failure theories can be divided into two categories. Time In-dependent theories (maximum normal stress theory, maximum shear Stress theory and von mises theory) determine the limiting stress, in which time dependent theories (fatigue, creep and fatigue creep interaction) predict the life time of any engineering design. An assessment for some theories in the two categories introduces accurate prediction of life time according to durability, reliability and integrity by interfacing with commercial FE code |
