| Abstract: | Abstract— Damage accumulation in both strain and stress control type fatigue tests are considered under duplex frequency loading conditions. The damage accumulation can be considered as a summation of damage due to static loading plus damage at each of the frequencies studied. An equation is derived that illustrates the distribution of total damage to failure under a variety of loading conditions. |
