Seismic Velocity of Chlorite Under High Pressure and Temperature and Implications for the Lesser Antilles Subduction Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Chlorite is thought to be one of the major water‐carrying phases in subduction zones, both within the slab and in the mantle wedge. Its presence has previously been linked to common seismological observations at subduction zones, including P and S wave anisotropy as well as high VP/VS ratios (>1.8) in the mantle wedge.

Brine Entrainment During Ice Shell Growth on Icy Worlds

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract The role of ocean composition in governing ice shell growth and ocean longevity on icy satellites remains poorly constrained. To address this, we develop a thermomechanical model of small to mid‐sized icy worlds that simulates ice shell growth from a saline ocean, explicitly quantifying brine entrainment through a parameterization of reactive ...

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1255-1268, September 2026.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

Thermo‐Mechanical Topology Optimization: An Immersed FEM Level‐Set‐Based Approach

International Journal for Numerical Methods in Engineering, Volume 127, Issue 15, 15 August 2026.
ABSTRACT This paper proposes a multi‐physics framework for topology optimization using an immersed level set‐finite element model. The work extends the capabilities of a recently developed immersed level‐set method to thermo‐mechanical problems, including coupling and material‐dependent properties.

Inverse source problems in thermoelasticity

In thermoelasticity, a parabolic equation for the temperature and a hyperbolic equation for the displacement of a body are coupled. In this research summary, an overview of the uniqueness results on inverse source problems in this setting is provided.In ...

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 ...

Optimisation of material composition in functionally graded plates for thermal stress relaxation using statistical design support system

Curved and Layered Structures
This study addresses the optimisation of material composition in a functionally graded plate for thermal stress relaxation, subjected to through-thickness thermal gradients, with the aim of minimising a stress utilisation ratio.

General Solutions for Three-Dimensional Thermoelasticity of Two-Dimensional Hexagonal Quasicrystals and an Application

, 2014
By introducing four displacement functions, the governing equations of the three-dimensional thermoelasticity of two-dimensional hexagonal quasicrystals are decoupled into two uncorrelated problems.
