Potential method in the theory of thermoelasticity for materials with triple voids

Archives of Mechanics, 2019
In the present paper the linear theory of thermoelasticity for isotropic and homogeneous solids with macro-, meso- and microporosity is considered. In this theory the independent variables are the displacement vector field, the changes of the volume ...

Spatial behaviour in dynamical thermoelasticity backward in time for porous media

, 2003
The aim of this paper is to study the spatial behaviour of the solutions to the boundary-final value problems associated with the linear theory of elastic materials with voids. More precisely the present study is devoted to porous materials with a memory

Analytical Modeling of Heat Transfer and Deformation Around a Circular Cavity in Elastic Ground

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3624-3651, 10 June 2026.
ABSTRACT The subsurface is increasingly exploited to host energy, utilities, and infrastructure systems that interact with surrounding soils and rocks through their thermal and functional operation. Prominent examples are provided by energy geostructures, district heating networks, buried power cables, steam and water pipes, and underground nuclear ...

Inverse Design Based on Nonlinear Thermoelastic Material Models Applied to Injection Molding

, 2019
This paper describes an inverse shape design method for thermoelastic bodies. With a known equilibrium shape as input, the focus of this paper is the determination of the corresponding initial shape of a body undergoing thermal expansion or contraction ...

Spin Transition of Fe3+ in δ‐(Al,Fe)OOH and Implication for Mid‐Lower Mantle Seismic Heterogeneities

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract δ‐(Al,Fe)OOH is an important water carrier and plays a critical role on Earth's deep water cycle. Lattice parameters of δ‐(Al0.89Fe0.11)OOH were measured by synchrotron single‐crystal X‐ray diffraction at simultaneously high temperature and pressure up to 65 GPa and 800 K in diamond anvil cells.

Naprężenia momentowe w termosprężystości

Engineering Transactions, 1968
The aim of the present paper is to generalize some theorems on the coupled thermoelasticity on a medium characterised by two vectors independent from each other: the displacement vector u and the rotation vector ω.

High Pressure Thermoelasticity of Body-centered Cubic Tantalum

, 2001
We have investigated the thermoelasticity of body-centered cubic (bcc) tantalum from first principles by using the linearized augmented plane wave (LAPW) and mixed--basis pseudopotential methods for pressures up to 400 GPa and temperatures up to 10000 K.

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

A Dynamic Problem of Thermoelasticity

Zeitschrift für Analysis und ihre Anwendungen, 1991
A space-periodic problem of nonlinear thermoelasticity is considered. For an elastic, linear, isotropic, homogeneous, nonviscous body in small geometry, we obtain a nonlinear system of equations. For small coefficient of the heat extension a we find a time-global weak solution of the initial-value problem.

Decoupling Seasonal Seismic Velocity Changes on Slow‐Moving Slopes in Southwest China Using Tree Ensemble Machine Learning

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Changes in seismic properties can help assess slope damage, which is influenced by external factors such as temperature, relative humidity, rainfall, air pressure, and local seismicity. However, the contributions of these factors, and how the dominant factor modulates transient and seasonal seismic velocity changes (δv/v $\delta v/v$), remain ...
