We perform smoothed particle hydrodynamics (SPH) simulations to study the material ejection from a grooved tin surface under unsupported shocks with different shock breakout pressures. It is found that melting has a substantial impact on both of the ejection morphology and spatial density distributions of ejecta. However, the failure depth of material approximates the width of the unsupported shock wave, independent of the shock breakout pressure.We perform smoothed particle hydrodynamics (SPH) simulations to study the material ejection from a grooved tin surface under unsupported shocks with different shock breakout pressures.
