Abstract: A general approach to calculating nonstationary thermoelastic stresses generated in solid objects as a result of absorption of the laser radiation energy is worked out in the quasi-static approximation. In the 3D model, analytic expressions are derived for the radial and tangential stress tensor components on the surface of the object.
