Abstract:

The present work was undertaken in connection with a study of detonation in explosives. It consisted of a photoelastic study of the development and propagation of stress and deformation in the neighborhood of an area of impact at the surface of a semi-infinite body. The intensity of a stress-wave in a body loaded by impact depends on the loading rate of the impact. In general, if a body is loaded mechanically, that is by collision with another body, only the quasi-static stress patterns will be of appreciable intensity. Very high loading rates, such as may be produced explosively, are required to produce stress-waves of an intensity such that they be visible photoelastically. Author
