Influence of static torsion and controlled modes on torsional fatigue were investigated in low cycle region under load- and deformation-controlled conditions. Fatigue life under in fully reversed torsion was independent of the loading mode controlled conditions. Addition of static torsion had little effect on the torsional fatigue life under deformation-controlled condition. However, the life decreased remarkably in load-controlled condition. A fatigue life evaluation model was proposed for load controlled torsion with static torsion. It was shown that predicted lives agree well with the actual fatigue lives of steels. Key Words, Low cycle, Static torsion, Controlled condition, Torsional fatigue
