Thermoelastic effects at low temperatures

Physica B+C, 1981
Abstract The temperature changes in a sample of vitreous silica subject to mechanical strains at frequencies of order 1Hz have been measured at low temperatures. The Gruneisen parameter γ has been determined from these experiments in the temperature range 1.5 – 10K. Below 4K, γ exhibits a marked strain dependence, but when extrapolated to zero strain

Analysis of Bioheat Transfer with Thermoelastic Effect

International Journal of Computational Methods
The development of thermal therapy always requires more reasonable temperature distribution predictions. Controlling the amount of heating is a common practice within general thermal therapy operations. This paper used a modified three-phase lag (TPL) bioheat transfer equation to describe the behavior of heat conduction in tissue with thermoelastic ...

Thermoelastic Effects on Shells

1993
In the entire text to this point, attention has been focused on the isothermal elastic behavior of classical shells. The effect that temperature distributions within the shell may have on stresses, strains and displacements has not been discussed.

THERMOELASTIC AND ELASTOPLASTIC EFFECTS MEASURED BY MEANS OF A STANDARD THERMOCAMERA

Experimental Techniques, 2004
It is well known that a metallic specimen changes its temperature when it is subjected to cyclic stresses. If the strain is elastic, the temperature change is produced by two main effects: elastoplasticity and thermoelasticity. The first phenomenon is due to microplasticity and energy dissipation inside a material that causes the conversion of ...

Effect of generalized thermoelasticity materials with memory

Structural Engineering and Mechanics, 2007
Many works have been done in classical theory of thermoelasticity in materials with memory by researchers like Nunziato, Chen and Gurtine and many others. No work is located in generalized thermoelasticity regarding materials with memory till date.

Effect of microtemperatures for micropolar thermoelastic bodies

Structural Engineering and Mechanics, 2017
In this paper we investigate the theory of micropolar thermoelastic bodies whose micro-particles possess microtemperatures. We transform the mixed initial boundary value problem into a temporally evolutionary equation on a Hilbert space and after that we prove the existence and uniqueness of the solution.

On second-order thermoelastic effects

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1964
Grundbeziehungen einer Theorie der Warmespannungen zweiter Ordnung werden aufgestellt, indem thermische Einflusse inBiots Elastizitatstheorie zweiter Ordnung einbezogen werden, oder, was dasselbe ist, indem Glieder zweiter Ordnung in lineare Beziehungen einer Warmespannungstheorie einbezogen werden, in einer Formulierung, die wiederum vonBiot vorgelegt

Low-temperature thermoelastic effects in glasses

Philosophical Magazine B, 1984
Abstract Thermoeiastic effects have been studied in vitreous silica and in polymethyl methacrylate (PMMA) by measuring the temperature response of a sample subjected to strain. Both ramp and sinusoidal strains were used, the latter covering the frequency range 0·01 to 10 Hz, in the temperature range 0·5 to 10 K.

Thermoelastic Effect in Niobium at the Superconducting Transition

Physical Review Letters, 1982
An abrupt decrease in acoustic loss Q/sup -1/ has been observed in flexural modes of polycrystalline Nb disk samples on cooling through the superconducting transition temperature T/sub c/. High-resolution measurements on a 1.6-kHz mode of one sample showed a 30% decrease in Q/sup -1/ in a 20-mK temperature interval.
