N2 - A consistent configuration formulation involving continuum damage mechanics based Lagrangian hydrodynamic computational framework is proposed to model 3D high- and hyper-velocity impact/damage/penetration problems. The contributions of the study are: (i) consistent formulation of the dynamic equation, contact formulation, constitutive relation, and time integration with respect to the same configuration; (ii) incorporate continuum damage mechanics into the hydrodynamic constitutive relations; and (iii) a robust time integration algorithm for the coupled equation of state and the internal energy equation. As a consequence, the present framework is robust and accurate for finite deformation contact/impact/damage/penetration applications, which is demonstrated by various numerical examples.
