Problems of Thermoelasticity

Progress in Aerospace Sciences, 1970
The dynamical problem of thermoelasticity +) for an elastic, isotropic, and centrosymmetric body consists in determining the stresses σji(x,t), μji(x,t) and deformations γji(x,t) aeji(x,t) of the classes C(1) and the functions , φ(x,t) and temperature θ(x,t) of the class C(2), for x ∈ V +A.

Thermoelasticity

1997
The important postulate that intermolecular interactions are independent of extent of deformation leads directly to the conclusion that such interactions cannot contribute to an energy of elastic deformation ΔEel at constant volume. In the earliest theories of rubberlike elasticity, it was additionally assumed that, intramolecular contributions to ΔEel

ON GENERALIZED THERMOELASTIC DIELECTRICS

Journal of Thermal Stresses, 1981
A complete nonlinear constitutive theory of thermoelastic dielectrics including polarization effects is derived by using a modified entropy production inequality proposed by Green and Laws [1] and independently by Suhubi [2].∗ The constitutive equations of thermorigid dielectrics are also obtained.

Thermoelastic stress concentrations.

Journal of Spacecraft and Rockets, 1966
Abstract : Thermal stress concentration factors were determined for rectangular flat plates, some of which were penetrated by holes and some which had filleted width changes. The experimental data indicate that the thermal stress concentration factors would be less than tension stress concentration factors for the same bars.

Direct Approach to Thermoelasticity

Journal of Thermal Stresses, 1979
The Laplace transforms with respect to time of the governing equations of one-dimensional thermoelasticity are obtained, with the displacement and temperature fields coupled. Elimination of the Laplace transform of either field variable between the resulting linear, simultaneous, and coupled ordinary differential equations results in ordinary ...

Plane Anisotropic Thermoelasticity

Journal of Applied Mechanics, 1984
The problem is formulated in terms of the three pairs of eigenvalues of the elasticity constants and the pair of eigenvalues of the heat conduction constants. Special attentions are given to the cases where the latter eigenvalue pair becomes equal to one or more pairs of the former group.

Thermoelastic Vibrations of a Beam

The Journal of the Acoustical Society of America, 1966
The equations of motion of a beam with the lateral surface thermally insulated are derived, including the effects of shear deformation and rotatory inertia. Thermoelastic coupling in the heat-conduction equation and in the elastic-constitutive relations is also included. Axial deformations of the beam are taken into account.

Thermoelastic Stresses in Beams

Journal of Applied Mechanics, 1960
The behavior of elastic, free beams of arbitrary constant cross section under an arbitrary temperature distribution is investigated. An analytical method of successive approximations for the solution of linear partial differential equations is applied to the solution for thermoelastic stresses in such beams. The stresses are obtained in terms of series,

Homogenization and Linear Thermoelasticity

SIAM Journal on Mathematical Analysis, 1983
We study homogenization of linear dynamic thermoelasticity with rapidly varying coefficients, using a semigroup approach. The resulting homogenized problem exhibits an unusual change in initial temperature.A formal asymptotic analysis predicts fast time oscillations in the temperature field.
