Hypervelocity impact tests have been performed on water ice in the velocity range of 3 to 7 km/s, by using low and high density projectiles. The projectile materials included polycarbonate and stainless steel, with diameter of 1.0 mm. The ice targets were solid cylinders at 253K made from pure water. The crater morphology in the solid ice caused by different projectile and different velocity were...
Smoothed particle hydrodynamics method (SPH) has a good adaptability for the simulation of free surface flow problems. However, there are some shortcomings of SPH which are still in open discussion. This paper puts forward a new image boundary processing method and particle arrangement method and applies it to simulate the hydrostatic of complex geometry tank and solitary wave attacking problem. The...
