Abstract:

A program was designed to demonstrate and evaluate the use of streak interferometry as a method for collecting temporally and spatially resolved transient deformation data on the surfaces of metallic solids. It is proposed that the technique has an important application in the establishment of constitutive relationships for solids transmitting elastic-plastic waves. The study showed that the technique can resolve displacement histories with times as short as 70 nanoseconds and measure surface velocities as large as 80 inches per second. These capabilities appear adequate for the intended applications. Representative data are shown and analyzed. Author
