Cyclic response and early damage evolution in multiaxial cyclic loading of 316L austenitic steel

Cyclic stress-strain response and fatigue damage character has been investigated in austenitic stainless steel 316L. Hollow cylindrical specimens were cyclically deformed in torsion and combined axial-torsion under constant strain rate condition and different constant strain and shear strain amplitudes. In-phase and 90° out-of-phase cyclic straining was applied and the stress and plastic strain response has been recorded. Cyclic...
