EFFECT OF HYDROSTATIC INITIAL STRESS IN ORTHOTROPIC GENERALIZED THERMOELASTIC HALF-SPACE

摘要

The present problem is concerned with the deformation of an orthotropic thermoelastic medium with hydrostatic initial stress, under the influence of mechanical/thermal source acting on the plane surface. The normal mode analysis is used to obtain the analytical expressions of the displacement components, force stress and temperature distribution. The numerical results are given and presented graphically for the Lord-Shulman theory of thermoelasticity [1] when mechanical/thermal source is applied. Comparisons are made in the presence and absence of hydrostatic initial stress and anisotropy.
