The Dynamic Behavior of Concrete

Abstract

A review of the current knowledge of the dynamic behavior of concrete is given. Summaries of related research studies performed by the academic community and the following defense contractors are presented: Aerospace Corporation, General Motors, Gulf General Atomic, Physics International, Terra Tek, and TRW. Particular attention is given in this review to rapid, impulsive loading of concrete resulting from mechanical impact and sudden exposure to radiation. Shock wave propagation and spallation phenomena are discussed. The coefficients for an existing constitutive model of a porous material are determined for a particular concrete. Numerical results based on this model and on an existing elastic-perfectly plastic model are given for several shock loading problems, and comparisons with corresponding experimental data are presented. The results indicate that neither model is adequate enough to predict with reasonable accuracy the shock effects in concrete. Recommendations for future research in these areas are given.
