Abstract :
In soft solids, such as biological tissue, the low value of shear elasticity allows the propagation of transverse waves with a high particle velocity when compared to the wave speed. With such a large Mach number shock waves can develop over a few wavelengths. We study the reflection of shocked shear waves traveling through a tissue-like medium, incident at a small angle on a free surface analytically and with numerical simulations.
