Modeling of ultra-high-speed impact at the surface of an elastic half-space
Abstract
A Semi-Analytical (SA) method is used to model impact loading at the free surface of an elastic half-space. The inertial effects are taken into account in the form of Green’s functions, also called influence coefficients. The influence coefficients are first computed and the simulation of an elastic shock with time-dependent surface pressure is performed. The effect of material properties, characteristic wave speed, the spatial distribution of the load, the impact size and the temporal form of the load is analyzed. It is observed that the dynamic response of a material which is submitted to dynamic loading depends strongly on the characteristic wave speed. The influence of the pressure pulse duration and peak magnitude is found to be also very significant, whereas the effect of the spot size and spatial distribution of the pressure is less significant.
