Assessment of foam fracture in sandwich beams using thermoelastic stress analysis

, 2009
Thermoelastic Stress Analysis (TSA) has been well established for determining crack-tip parameters in metallic materials. This paper examines its ability to determine accurately the crack-tip parameters for PVC foam used in sandwich ...

On Stability of Hyperbolic Thermoelastic Reissner-Mindlin-Timoshenko Plates

, 2013
In the present article, we consider a thermoelastic plate of Reissner-Mindlin-Timoshenko type with the hyperbolic heat conduction arising from Cattaneo's law. In the absense of any additional mechanical dissipations, the system is often not even strongly

On nonlinear strain vectors and tensors in continuum theories of mechanics

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
A non-linear mathematical model of hyperbolic thermoelastic continuum with fine microstructure is proposed. The model is described in terms of 4-covariant field theoretical formalism.

Frequency and surface dependence of the mechanical loss in fused silica

, 2005
We have compiled measurements of the mechanical loss in fused silica from samples spanning a wide range of geometries and resonant frequency in order to model the known variation of the loss with frequency and surface-to-volume ratio.

Thermodynamical fluctuations in optical mirror coatings

, 2003
Thermodynamical fluctuations of temperature in mirrors may produce surface fluctuations not only through thermal expansion in mirror body but also through thermal expansion in mirror coating.

A nonlocal photoacoustic effect with variable thermal conductivity of semiconductor material subjected to laser heat source

Results in Physics
This study explores the behavior of laser-exposed photo-excited carriers, investigating the propagation of photoacoustic waves in the thermoelastic domain. It also delves into the theoretical generation of surface acoustic waves in semiconductors through

A novel model of photoacoustic and thermalelectronic waves in semiconductor material

AIP Advances
We explore theoretically the photoacoustic wave propagation created by the photoexcited carrier diffusion in the thermoelastic domain. Consideration is given to the coupling of acoustic and thermomechanical waves.
