We present an analysis of energy deposition into a hyperelastic solid induced by a shock impact from an explosive blast. Ecoflex 00-30 is used for the solid object and the shock is generated by a finite sized charge of HMX explosive that generates a shock in air. The solid sphere shaped rubber-like material is modeled by the Neo-Hookean equation of state (EOS), while for HMX the Wide-Ranging EOS is used. The diameters of the explosive charge and the solid object are 1.0 and 3.0 inches respectively, and the distance between their centers is 16.0 inches. Gauges were placed on the surface and inside the sphere to measure pressure and compare numerical results from our novel multi-material simulation code with experimental data generated by Prof. Glumac’s group at the University of Illinois. Both experiments and numerical simulations exhibit high frequency oscillations in the sphere.
