WebFluctuating Stresses: The components are subjected to forces, which are not static, but vary in magnitude with respect to time. The stresses induced due to such forces are called Fluctuating Stresses. The most popular model for stress–time relationship is the sine curve. There are three types of mathematical models for cyclic stresses:
