Design for fluctuating stresses
WebWhen a machine component is subjected to fluctuating stresses, there forms a mean stress σ m and stress amplitude σ a. It has been observed that σ m has an effect on the fatigue failure of the component when the component undergoes functionality with an alternating component.
