Shock-Wave Attenuation in Elastic-Rigid Foams

Abstract

Described are experimental techniques for the study of the response of foamed or distended materials to impact loading and the results of applying these techniques to four different kinds of foam -- polyurethane, aluminum, silica, and graphite. An approximate theory for calculating the behavior of elastic-rigid locking solids is developed and applied to the materials tested. Within certain limits agreement with experiment is good, and at least for some materials within a range of impact momenta the internal pressure history can be logically related to measurements of quasi-static compression, although better agreement is possible when certain parameters are measured dynamically.
