The effects of static pre-strain (1/4 cycle) and cyclic pre-strain on the low cycle fatigue life of Type 316L austenitic stainless steel were investigated. Static pre-strain amplitude which leads to the significant decrease of fatigue life was different depending on the value of cyclic plastic strain range in low cycle fatigue test. The same tendency was observed in the effect of both static and cyclic pre-strain on the low cycle fatigue life of stainless steel.
