Comparison of mechanical properties in tension and shear at high strain rate for AISI 316 and ARMCO iron
Stress-strain curves up to very high strain rates (3 x 1.0 E4/s), determined by shear testing of AISI 316 and ARMCO iron, showed large strain at fracture and saturation of flow stress (no strain hardening) at large strains. The flow curves in tension showed strain hardening up to fracture. The different macroscopic responses in tension and shear are caused by differences in the corresponding microscopic deformation mechanisms. The flow curves in tension and the equivalent flow curves in shear were not coincident because the classical plasticity model assumes the same microscopic deformation mechanism at each deformation mode.
