Equations governing the response of composite materials to shock loading are presented and used to predict Hugoniot curves for several two- constituent composites called Elkonites. Special attention is given to the transfer of thermal energy between constituents within the shock surface. It is shown that although energy transfer has little effect on the composite Hugoniot, it can change the predicted constituent states remarkably. Hugoniots for several Elkonites are calculated and compared with experi mental data.
