摘要:

The linear theory of thermoelasticity without energy dissipation for homogeneous and isotropic materials is employed to study one-dimensional waves in a half-space. The waves are supposed to be due to sudden inputs of temperature and stress/strain on the boundary. The Laplace transform method is employed to solve the problem. Exact solutions, in closed form, for the displacement, temperature, strain, and stress fields are obtained. The characteristic features of the underlying theory are analyzed in light of these solutions and their counterparts in earlier works.

摘要:

This article presents an analysis of the free vibrations of a truncated conical thin shell subjected to thermal gradients. The governing equations of the shell are based on the Donnell-Mushtari theory of thin shells. Simply supported and clamped boundary conditions are considered at both ends of truncated conical shell. Temperature loading due to supersonic flow is assumed to vary along the meridian and across the thickness of the shell Hamilton's principle is used to derive the appropriate governing equations of a conical shell with temperature-dependent material properties. The shell material has a kind of inhomogeneity due to the varying temperature load and temperature dependency of material properties. The resulting differential equations are solved numerically using the collocation method. The results are compared with certain earlier results. The influence of temperature load on the vibration characteristics is examined for the conical shells with various geometrical properties.

摘要:

A theory of thermoelasticity for nonsimple materials is derived within the framework of extended thermodynamics. The theory is linearized, and a uniqueness result is presented. A Galerkin type solution of the field equations and fundamental solutions for steady vibrations are also studied.

摘要:

The effect of two relaxation times, following Green and Lindsay's theory, on the reflection of thermoelastic waves at a homogeneous, isotropic, and thermally conducting elastic solid half-space is studied. The results for the partition of the energy for various values of the angle of incidence are presented and compared with that of Lord and Shulman's theory to show the importance of the second relaxation time.

摘要:

This article addresses the problem of thermal stresses for isotropic microstretch elastic cylinders subjected to a temperature distribution that is linear in the axial coordinate. A direct method is used to reduce the problem to solving plane strain problems. The results are used to study the deformation of circular cylinders.
