A generalized thermoelasticity problem of an annular cylinder with temperature-dependent density and material properties

A generalized thermoelasticity problem of an annular cylinder with temperature-dependent density and material properties
In this paper, the problem of generalized thermoelasticity with one relaxation time for an infinite annular cylinder of temperature dependent physical properties is discussed. Both the inner and outer curved surfaces of the cylinder are considered stress free. The inner surface is subjected to decaying with time and temperature whereas the outer surface is maintained at a reference temperature. A ... Read more

Eigenvalue approach in a three-dimensional generalized thermoelastic interactions with temperature-dependent material properties

2018-10-02 16:26:42 Keywords temperature-dependent, thermoelasti, eigenvalue approach, Three-dimensional,
Eigenvalue approach in a three-dimensional generalized thermoelastic interactions with temperature-dependent material properties
A three-dimensional model of the generalized thermoelasticity without energy dissipation under temperature-dependent mechanical properties is established. The modulus of elasticity is taken as a linear function of the reference temperature. The resulting formulation in the context of Green and Naghdi model II is applied to a half-space subjected to a time-dependent heat source and traction free surface. The normal mode ... Read more
