This is less than half the critical strain of shear band nucleation (0.53) in as-is AISI 4340. Additional experiments at smaller global strains (via thicker-walled copper stopper tubes) are required to identify critical strain for shear band nucleation in this steel. At larger global strain, the sample was deformed at a post-critical stage
WebThis work analyses the prediction capabilities of a recently developed critical plane model, called the SKS method. The study uses multiaxial fatigue data for S355-J2G3 steel, with in-phase and 90° out-of-phase sinusoidal axial-torsional straining in both the low cycle fatigue and high cycle fatigue ranges. The SKS damage parameter includes the effect of …
