Abstract
High strength materials such as used as armor plate have
been investigated in torsion using Split Hopkinson Bars for the purpose of
obtaining stress-strain curves and for examining the mechanism of plastic
deformation in terms of mechanical instability due to thermal softening at
high strain rates. A comparative study of the plastic deformation behavior
of RHA steel, Aluminum 5083 H131 alloy and Tungsten A90S alloy under the
loading condition at high strain rates is carried out and the effect of
strain rate on shear flow stress and stress-strain profiles is presented.
Strain rate sensitivities of the materials are evaluated and discussed with
respect to mechanical instability and adiabatic shear strain localization.
