PROPERTIES OF SPHERICAL STRESS WAVES PRODUCED BY HYPERVELOCITY IMPACT,
Abstract
A semi-empirical model is derived which will, it is hoped, contribute to the understanding of the nature of waves and fractures in solids caused by hypervelocity impact. The distance within a solid at which the shock wave slows down to an elastic wave is considered as the radius of a cavity to the surface of which a forcing function can be applied to produce an elastic wave similar to that produced by the impact of a high velocity projectile. By the use of high-speed computer, the characteristics of the forcing function are found which will produce the same effects as those caused by a projectile. This forcing function can be described by a mathematical series, each term being of form for which the general wave equation can be solved. This permits the computation of particle displacement, particle velocity, and principal stresses within the target. (Author)
