SIF Determination with Thermoelastic Stress Analysis

Procedia Structural Integrity, 2016
AbstractThis work is focused on the experimental determination of the stress intensity factor (SIF) using thermoelastic stress analysis (TSA) for a compact tension specimen during a fatigue crack growth test. A comparison of the stress field obtained with computational modelling, finite element method, against the experimental data obtained with the ...

High‐Pressure Elasticity of CAS Phase and Its Implications for the Fate of Subducted Anorthosite Crust

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The CAS phase (CaAl4Si2O11) is a key phase formed in subducted silica‐alumina rich crustal and sedimentary materials under the mantle transition zone conditions. In this study, its elastic properties were investigated using first‐principles calculations up to 30 GPa.

Thermoelastic Stress and Damage Analysis Using Transient Loading [PDF]

Experimental Mechanics, 2009
Thermoelastic stress analysis (TSA) is often regarded as a laboratory based technique due to its requirement for a cyclic load. A modified methodology is proposed in which only a single transient load is used for the TSA measurement. Two methods of imparting the transient load are validated against calculations and the conventional TSA approach ...

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 ...

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 ...

Statistical Characterization of Thermoelastic Internal Stress in TATB-Textured PBX via Computational Micromechanics

Crystals
TATB (1,3,5-triamino-2,4,6-trinitrobenzene) crystals exhibit strong thermoelastic anisotropy, making crystallographic texture a key factor in the thermal-stress response of TATB-based polymer-bonded explosives (PBXs).

Tribological Performance of 60NiTi Alloy Under Varying Contact Conditions and Elevated Temperatures in Linear Reciprocating Sliding

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐
