Stability of Multidimensional Thermoelastic Contact Discontinuities [PDF]

Archive for Rational Mechanics and Analysis 237 (2020), no. 3, 1271--1323, 2019
We study the system of nonisentropic thermoelasticity describing the motion of thermoelastic nonconductors of heat in two and three spatial dimensions, where the frame-indifferent constitutive relation generalizes that for compressible neo-Hookean materials. Thermoelastic contact discontinuities are characteristic discontinuities for which the velocity

Crack paths under mixed mode loading [PDF]

, 2008
Long fatigue cracks that initially experience mixed mode displacements usually change direction in response to cyclic elastic stresses. Eventually the cracks tend to orient themselves into a pure mode I condition, but the path that they take can be ...

Tailoring strength and ionic conductivity in zirconia‐based solid oxide electrolytes using a multimaterial approach

Journal of the American Ceramic Society, EarlyView.
Abstract A multimaterial approach is explored for tailoring the mechanical and functional properties of zirconia‐based ceramic electrolytes to be employed in electrochemical solid oxide cells (SOCs). The combination of alumina‐toughened zirconia (ATZ) surface layers with an embedded 8 mol% yttria‐stabilized zirconia (8YSZ) core layer introduces ...

Photothermal excitation processes with refined multi dual phase-lags theory for semiconductor elastic medium

Alexandria Engineering Journal, 2020
The aim of this investigation is to study a refined multi-phase-lags generalized thermoelasticity theory and coupled plasma theory for a semi-infinite semiconductor elastic medium. The model is studied in context of the Photothermal transport process for

PLANE WAVES AT AN INTERFACE OF THERMOELASTIC AND MAGNETO-THERMOELASTIC MEDIA

Mathematical Modelling and Analysis
This research examines the propagation of waves in a semi-infinite, isotropic magneto-thermoelastic solid, and a semi-infinite thermoelastic solid with welded contact. The study investigates the influence of a magnetic field on amplitude coefficients for the incidence of thermal, SV, and P waves in the magnetothermoelastic solid in a semi-infinite ...

A note on exponential stability of a thermoelastic system with internal delay [PDF]

arXiv, 2022
The presence of a delay in a thermoelastic system destroys the well-posedness and the stabilizing effect of the heat conduction. To avoid this problem we add to the system, at the delayed equation, a Kelvin-Voigt damping. In this note we point on the exponential stability of such system in order to improve the mean result in our paper Well-posedness ...

Dynamics of thermoelastic thin plates: A comparison of four theories

, 2005
Four distinct theories describing the flexural motion of thermoelastic thin plates are compared. The theories are due to Chadwick, Lagnese and Lions, Simmonds, and Norris.

Bio‐inspired damage‐tolerant alumina‐based layered ceramics through rapid sintering

Journal of the American Ceramic Society, EarlyView.
Strategy to enhance damage tolerance in alumina‐based ceramics through a layered architecture with tailored microstructure using rapid sintering. Abstract Layered ceramics have proved effective under contact damage or thermal shock, associated with the effect of compressive residual stresses and/or textured microstructure against surface crack ...

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.

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
