ATTENUATION OF THE STRONG PLANE SHOCK PRODUCED IN A SOLID BY HYPERVELOCITY IMPACT

Abstract

The attenuation of strong plane shocks in solids produced by hypervelocity impact is studied, and two parametric equations are developed which describe the path of the shock front in the x,tplane. These parametric equations were derived by considering the entropy change across the decaying shock and assuming that the characteristic lines behind the shock are straight lines. The equation of state is approximated by simple Hugoniot and isentrope equations. The same problem is also solved graphically by a stepwise characteristic method. A comparison of the graphical and analytical results shows that the simplifying assumptions made for the analytical solution are valid for both weak and strong shocks.
