THERMOELASTIC BENDING RESPONSE OF ANGEL-PLY COMPOSITE PLATES RESTING ON ELASTIC FOUNDATIONS
Different plate theories are presented to study the thermoelastic response of a multilayered angle-ply composite plate. The plate is subjected to a sinusoidal temperature and resting on different types of elastic foundations. The effects due to thermal loads and elastic foundations parameters as well as the variation of lamination angle are studied. Numerical results suggest that Pasternak's model should be ... Read more

Two-temperature generalized thermoelasticity under ramp-type heating by finite element method
In this work, a general finite element model is proposed to analyze transient phenomena in thermoelastic half-space filled with an elastic material, which has constant elastic parameters. The governing equations are taken in the context of the two-temperature generalized thermoelasticity theory (Youssef in IMA J. Appl. Math. 71(3):383–390, 2006). A linear temperature ramping function is used to more realistically model ... Read more

On the initial stress, magnetic field, voids and rotation effects on plane waves in generalized thermoelasticity
In this work, we study the effect of the magnetic field, rotation, thermal field, and the initial stress and also voids on the reflection of P-wave with one relaxation time. The formulation is applied to generalization, the Lord–Shulman theory with one relaxation time. The electromagneto-thermoelastic interactions in perfectly conducting plane is subjected to a uniform axial magnetic field with voids ... Read more

Deformation due to thermal source in micropolar generalized thermoelastic half-space by finite element method
The present investigation deals with deformation in micropolar generalized thermoelastic materials due to thermal source. Lord-Shulman (LS) (1967) and Grren-Lindsay (GL) (1972) theories are used to study the problem. As an application of the approach, a particular type of thermal source is considered and the problem is solved by finite element method. The components of displacement, microrotation, stress and temperature ... Read more

Nonlinear transient thermal stress analysis of thick-walled FGM cylinder with temperature-dependent material properties
In this paper, the problem of generalized thermoelasticity in a thick-walled FGM cylinder with one relaxation time is presented. The material properties are taking as function of temperature and graded in the radial. Due to the nonlinearity of the governing equations, finite element method is adopted to solve such problem.

Nonlinear Transient Thermal Stress Analysis of Temperature-Dependent Hollow Cylinders Using a Finite Element Model
In this paper, the nonlinear transient thermal stress analysis is conducted for temperature-dependent hollow cylinders subjected to a decaying-with-time thermal field.

A finite element method is used to study the dual-phase-lag model on thermoelastic interactions in a semi-infinite medium subjected to a ramp-type heating. The governing equations are taken in a unified system from which the field equations for coupled thermoelasticity as well as for Lord and Shulman theory can be easily obtained as particular cases.
