Abstract

A-T model of the modified hydrodynamics, is widely used in metal projectile and target materials, good prediction accuracy for penetration depth in penetration process. But the Rt (target defense force) is determined relatively difficult, lack of real physical meaning to widely accepted the Rt of calculation model. Based on the role of the existence of adiabatic shear failure mechanism between projectile and target, the Rt is endowed with real physical meaning, It can be better reflected the failure mechanism of target plate for influence of the thermal effect and strain rate in penetration. Theoretical model calculation is carried out under the Rt of new mechanism, The results are in good agreement with the experimental and simulation results.
