In this work, a generalized solution for the thermoelastic plane wave in a semi-infinite solid induced by pulsed laser heating is developed. The solution takes into account the non-Fourier effect in heat conduction and the coupling effect between temperature and strain rate, which play significant roles in ultrashort pulsed laser heating. Based on this solution, calculations are conducted to st...
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...
Abstract In this paper, we investigate the decay properties of thermoelastic suspension bridges model. We prove that energy is decaying exponentially. To our knowledge, result new and method proof based on to build appropriate Lyapunov functional.
This paper presents the application of the finite element method to two inverse problems in solid mechanics. In the first application, a formulation for the inverse detection of unknown boundary conditions for thermoelastic problems is detailed. The second application involves the inverse determination of heterogeneous material properties for a loaded structure. Both approaches involve the use ...
In this paper, we will highlight the current research which employs the topology optimization to extensional transducers, and porous material microstructures with unusual thermoelastic properties. These examples demonstrate that the topology optimization problem in...
This paper deals with the effects of friction material properties on thermoelastic instability (TEI) and the associated dominant deformation mode. Both analytical and finite element models are constructed for determining the variation of the critical speed and the dominant TEI mode. Some important factors, e.g. the nonconductive friction material as well as the symmetric and anti-symmetric TEI ...
this paper presents a nonlinear model of a clamped-clamped microbeam actuated by an electrostatic load with stretching and thermoelastic effects. the frequency of free vibration is calculated by discretization based on the differential quadrature (dq) method. by separating the real and imaginary parts of frequency, the quality factor of thermoelastic damping is calculated. both the stretching a...
