Abstract
Simple wave solutions are presented for the case of pressure shear waves in a hyperelastic material which models fused silica. The adiabatic strain energy function of this material is written as an expansion to third‐order terms in the strains. The analysis includes interaction of the simple waves with a free surface. Comparison of computed particle velocity‐time profiles for the free surface with profiles observed in experiments shows good agreement. The solutions also indicate that the shear wave propagating in a shear‐strain‐free region of fused silica is essentially nondispersive.Keywords
