It is shown that the arising maximal strength of the thermoelastic waves exceeds hundred times ultimate strength of a samples material on the axis of a track. The time dependence of the electron gas and ion lattice temperatures, of the thermoelastic waves strength are determined at a diﬀerent distance from center of track. The time dynamic change is also determined of the maximal region within which thermoelastic strength exceeds ultimate strength of a samples material. By moving away from the center of a track along the radius, the amplitude of the thermoelastic waves will decrease inversely proportional to the radius.thermoelasticitythermoelastic wavesnumerical simulationdeformationstressthermal spike modelтермоупругостьчисленное моделированиедеформациянапряжениемодель термического пика
