To investigate the fatigue behavior of Type 08X 18H I OT stainless steels and titanium alloys BT9 strain controlled tests under 12 proportional and nonproportional loading ar room temperature were carried out. A strain parameter. namely, a nonproportional strain range. is proposed to obtain a correlative dependence with lifetime. For the majority or the materials this dependence can be derived from uniaxial tests and described by a linear function. It made it possible to propose simple engineering method for lifetime prediction.}, type={Article}, title={Low-cycle fatigue strain criterion for biaxial nonproportionul loading}, URL={http://www.journals.pan.pl/Content/125186/PDF/4_MECHANICAL_48_2001_1_Shukayev_Low.pdf}, keywords={low-cvcle fatigue, life prediction}, }
