RESEARCH ON KINETICS OF DEFORMATION AND FRACTURE.

Abstract

A high speed electronic photographic device, an image convertor, was constructed to record the kinetics of fracture in metal samples. The image convertor is capable of photographing at a framing rate as rapid as 2 million frames per second with as short an exposure time as 0.1 microseconds. Also assembled and constructed were an impact tensile apparatus, a high intensity light source, and a complex of electronic synchronizing mechanisms. The image convertor and its accompanying equipment have been successfully synchronized. Photographs of cracks passing through polycrystalline zinc samples were obtained. (Author)
