The problem of definition of loading’s cycle and fatigue life in case of asynchronous loadings is not fully solved in the literature. A few different approaches can be found, but none of them is widely accepted. In this work, an energy based definition of loading’s cycle for asynchronous loadings is proposed. The method uses plastic strain energy density of complex loading’s components as a weightening factors to calculate weighted arithmetic mean of loading’s components lives.
