- Abstract
The residual stress-strain state of a disk caused by the action of a laser pulse or an electron beam is investigated within the framework of the dynamic statement of the coupled problem of thermomechanics. The axially symmetric problem is solved numerically using the thermodynamically consistent theory of the inelastic behavior of the material involving the finite-element method and taking into account temperature dependences of physical and mechanical characteristics of the material. The response of the material to thermal irradiation followed by gradual cooling is studied, and the possibility of formation of surface profiles with the use of only thermal treatment is considered.
