Abstract

The dynamic crush behavior of Hyperelastic Sandwich Coatings is investigated in this paper. Without loss of generality, a unit periodic cell of the coating is studied, including Wave transmission and the crush energy attenuating . The initial imperfection plays an important role in Crush Dynamics. Inertial effect enhances the stress plateau greatly. Stabilization of cores against buckling has a great attenuating effect under shock environment. These effects are illustrated and quantified with the aid of detailed numerical calculations and Experiment.

Key words
