In a disk with an oscillatory deformation from an axisymmetric state with frequency ωD and azimuthal wavenumber mD, two normal mode oscillations with a set of frequency and azimuthal wavenumber being (ω1, m1) and (ω2, m2) are resonantly coupled to each other through the disk deformation when the resonant conditions (ω1 + ω2 + ωD = 0 and m1 + m2 + mD = 0) are satisfied. In the case of hydrodynam...

This paper is concerned with the airway closure problem and investigates the quasi-steady deformation characteristics of strongly collapsed (buckled) airways occluded by liquid bridges of high surface tension. The airway wall is modeled as a thin-walled elastic shell, which deforms in response to an external pressure and to the compression due to the surface tension of the liquid bridge. The go...

The theory of generalized thermoelastic diffusion, based on the theory of Lord and Shulman, is used to study the thermoelastic-diffusion interactions in an infinitely long solid cylinder subjected to a thermal shock on its surface which is in contact with a permeating substance. By means of the Laplace transform and numerical Laplace inversion the problem is solved. Numerical results predict fi...

In this paper, the vibrations of thin plate in modified couple stress thermoelastic medium by using Kirchhoff- Love plate theory has been investigated. The governing equations of motion and heat conduction equation for Lord Shulman (L-S) [1] theory are written with the help of Kirchhoff- Love plate theory. The thermoelastic damping of micro-beam resonators is analyzed by using the normal mode a...

The thermomechanical properties of thermal barrier coatings (TBCs) such as elastic modulus, thermal conductivity, and coefficient of thermal expansions are determined by pores, cracks, and splat boundaries, which affect the thermoelastic properties of thermally grown oxide (TGO) layer and the fracture behavior in TBCs. The thermoelastic characteristics thus have been investigated through mathem...

A thermoelastohydrodynamic (TEHD) coupling model is developed to study the static performance of a heavy-duty tilting pad thrust bearing (TPTB) under effect axis misalignment. To ensure validity in calculating thermoelastic deformation, calculation accuracy mechanical and thermal deformations used TEHD verified by finite element method (FEM). The influence on flow state prediction determined us...

Under the action of a stationary heat source, we construct Boussinesq functions problem thermoelasticity under conditions plane deformation semiinfinite body with free, rigidly, smoothly, or flexibly fastened boundary either kept at zero temperature thermally insulated. The construction is reduced to solving boundary-value problems for harmonic in half space. Relations displacements and stresse...

A statistical distribution for an adiabatically isolated body is proposed and its temperature defined as a function of given energy. It obtained result the generalization ensemble oscillators, in which probability proportional to time motion on each small section oscillator trajectory phase space. This makes it possible explain thermoelastic effect --- dependence deformation under adiabatic mec...

We characterize thermally-induced effects in an optical resonator illuminated with high-power laser radiation. From thermoelastic deformation of a mirror’s surface, we observe degeneracy of higher-order spatial modes with the fundamental mode that leads to power transmission limits and thermally-induced power fluctuations using a ring resonator with calibrated absorption loss. A model used to p...
