Materials response to large plastic deformation

This chapter addresses the influence of deformation mode, crystal structure, material purity, and alloying on stress-strain behavior. Focuses on low strain rate data but attempts to show trends which are also important for large strain, high strain rate predictions. Examines experimental techniques, aluminium and aluminium alloys, copper, nickel, 70-30 brass, and bcc iron and iron alloys. Points out that strain hardening at large plastic strains cannot be inferred from small-strain tensile tests. Finds that saturation (steady state behavior) of the flow stress in fcc materials is not universal. Notes that most metals and alloys at room temperature do not reach steady state saturation at strain levels of 3 to 5
