摘要

A dynamic problem in a thermoviscoelastic material with rotation is investigated for the disturbance duc to thermomechanical sources. To solve the problem the Laplace and Fourier transform techniques are applied. Concentrated and uniformly distributed sources are taken as an application of the approach. A numerical inversion technique is used to invert the integral transform and to obtain the components of displacement, stress and temperature distribution in the physical domain. The effect of rotation and viscosity is examined on the resulting quantities and depicted graphically for a specific model .Some special case are also deduced from the present investigation.
