Keywords:

Abstract
The paper presents the numerical analysis of normal impact of 1 kg soft body impacting a rigid target at a speed of 100 m/s by using smoothed particle hydrodynamics method. The fields of pressure, density and velocity distributions in the soft body for different time have been calculated. The fields of the physical parameters being analyzed are transient and have spatial inhomogeneity. Analysis of the obtained results allows us to make a conclusion about the wave nature of these fields.Downloads
