Аннотация:
In the present paper, the model of generalized thermo-viscoelastic theory with fractional relaxation operators is used to capture the microscale responses of viscoelastic metal film irradiated uniformly by a laser pulse heat flux with non-Gaussian form. Employing Laplace transform as a tool, the problem has been solved analytically in the transformed domain. The inverse transforms are obtained by using a numerical method based on Fourier expansion techniques. The effects of fractional relaxation operators and viscoelastic property on the responses of the metal film are discussed and illustrated graphically.
