Abstract: A mathematical model of the evolution of the thermoelastic momentum arising in metal exposed to an ion source is investigated. On the basis of the numerical calculation a relation of the thermoelastic wave form with the form and the location of the source as well as a condition of extension and puting out of the thermoelastic waves are studied. A temperature influence on the velocity of the thermoelastic waves is established.

Keywords: Thermoelastic waves, function source, ion beam, initial and boundary conditions
