摘要：
In the present work, we are interested in the three-dimensional description of the behaviour of a high strength material susceptible to adiabatic shear banding. The high strain rate constitutive model, based on irreversible thermodynamics, has been formulated in order to be applied in the context of high-velocity impact and penetration mechanics, and has been implemented as 'user material' in the finite element code LS-DYNA. Some preliminary numerical results are shown in the case of the loading of a plate hat specimen between Hopkinson pressure bars.
