Fatigue expectations traditionally have been formulated during the experimental stage of product development to evaluate unexpected failures seen in proving-ground vehicle testing or to define procedures for accelerated laboratory bench tests. A key feature of the modern durability design process is integration of computing methods with finite-element analysis (FEA) to predict durability early in design. In the automotive industry, early evaluation of fatigue performance can increase reliability and reduce product development time.
