Abstract :
Summary form only given, as follows. High power lasers were used to create shock waves in metals with pulse duration in the domain of 10 ps to 10 ns. The release of these shock waves from the material are used to determine the ultimate strength. The tension strength and the strain rate in the metal were measured with an optically recording velocity interferometer system (ORVIS). The ultimate strength in Al and Cu were achieved at a strain rate about 10/sup 8/ [1/sec]. The measured values of the ultimate strength in Al and Cu are consistent with the calculated values from our wide range equation of state.
