PLASTIC YIELD AND REVERSE YIELD WAVES GENERATED BY IMPULSIVE ELECTROMAGNETIC RADIATION.

Abstract

Absorption of radiation through a thin layer adjacent to an irradiated, stress free, surface causes rapid heating and the generation of stress waves. Temperature rises sufficient to cause plastic yielding in the initial stress jump and reverse yielding during the subsequent wave propagation are considered under the assumption of uni-axial strain. An elastic-plastic wave solution is constructed and compared with the purely elastic solution. In particular the reduced compressive and tensile stresses in the outgoing wave, and the pulse spread, are illustrated. (Author)
