Time-resolved measurements of copper at shock induced high pressures and temperatures are used to illustrate the capability of using such techniques to investigate high pressure strength. Continuous shock loading and release wave profiles were made to 93 GPa using veocity interferometric techniques. Fine structure in the release wave profiles from the shocked state indicates an increase in shear strength of copper to 1.5 GPa at 93 GPa from its ambient value of 0.08 GPa.
