Abstract
Laser shock hardening consists in the action on a sample of a pressure pulse generated by the plasma of the sample surface layer vaporized by short high-energy laser pulses. To model the change in the properties of the material under the action of pulsed mechanical stresses, it is necessary to know the space-time dependence of the pressure acting on the sample subject to the parameters of the laser pulse and the properties of the evaporated material. This paper presents a model and calculation of the time dependence of the pressure acting on a sample as a result of evaporation of the absorbing material and the development of plasma optical breakdown.
期刊介绍：
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
