The dynamic fatigue-life equation is applied to the uniaxial tensile test. On this study, we show that the fatigue limit values can be extracted from the tensile testing data. Consequently, those experi-ments can be correlated and the fatigue limit can be found by the tensile test. The theory is verified by comparing the theoretical fatigue limit from tensile test to experimental fatigue limit from fatigue test. The results can be used to find the reliable fatigue limit by tensile test.

In this paper, the Optimum Design concept is introduced by deter-mining the detailed design so it satisfies the given constrained con-dition. Also shows the process of determining the design variable for minimizing the object function. Finite element analysis is used for predicting the structural behavior and design sensitivity analysis by adjoint variable method is used for changing of predicting behavior. Adjoint variable method is introduced, and to prove the optimiza-tion theories tower crane model is used.
