WebJun 22, 2016 · A novel theory of cumulative fatigue damage is presented. It is based on Continuum Damage Mechanics approach which relates the damage rate to that of cyclic loading through the damage function. A new damage function related to isodamage lines and remaining life aspects is analyzed. The final result is a nonlinear fatigue damage rule. WebAbstract. A number of the cumulative-damage theories which are currently available have been reviewed. Significant assumptions regarding the manner in which fatigue damage is assumed to occur at different stress levels when these stress levels occur alone and when they are mixed are also delineated. On this basis the several theories are ...
