Model description of thermoelastic stress in materials under bombardment by heavy ions

Abstract

In our previous papers, the processes of formation and evolution of thermoelastic waves produced in metals under the action of powerful pulsed beams of small-energy ions were studied using the system of thermoelasticity equations. In this paper, the detailed numerical study of thermoelasticity processes taking into account temperature effects in the electronic and lattice subsystems is carried out using a temperature model of the thermal peak and the system of thermoelasticity equations in the case of propagation of a heavy ion through a condensed medium. New data and dependences are obtained. An analysis involving the comparison between the obtained results and the results of previous papers is presented.
