Since wear resistance and fatigue strength are key requirements for chassis components, induction hardening is widely used to apply compressive stress for controlling crack growth. Therefore, it is crucial that the influence of defects is examined with compressive residual stress applied to parts. In this report, the relationship between crack depth and compressive residual stress is evaluated using a cylindrical specimen and a torsional fatigue test. The test results were found to be consistent with CAE simulations performed in advance. In the future, it will be necessary to make this method applicable to product design to further improve vehicle safety performance.
