  • J0560201 Thermal Fatigue of Pipes Induced by Fluid Temperature Change : Effect of Multiaxial Pre-loading on Fatigue Strength

抄録

This study investigates an effect of pre-inelastic multiaxial loading on failure lives in a followed high cycle fatigue test for SUS316 steel. In the multiaxial low cycle fatigue test for the pre-loading, two types of strain paths were employed which are a push-pull straining and a circle straining. The circle straining is the non-proportional loading in which axial strain £ and shear strain γ has 90 degree phase difference. Using the specimen fatigued in the pre-loading test, high cycle fatigue test was conducted by a rotating bending fatigue testing machine. Based on the obtained results, property of failure life in high cycle fatigue which received pre-loading under non-proportional loading is discussed.
