Abstract : Absorption of radiation through a thin layer adjacent to irradiated, stress-free, surface causes rapid heating and the generation of stress waves. Temperature rises sufficient to cause plastic yielding are considered, and a resulting elastic-plastic wave solution is constructed. Comparison is made with the purely elastic solution, and in particular the reduced amplitude and pulse spread of the outgoing tensile wave is illustrated. (Author)
