Detection and tracking of cracks based on thermoelastic stress analysis [PDF]

Royal Society Open Science, 2020
Thermoelastic stress analysis using arrays of small, low-cost detectors has the potential to be used in structural health monitoring. However, evaluation of the collected data is challenging using traditional methods, due to the lower resolution of these

Osteoporotic Bone Quality Significantly Increases Proximal Stress Concentration: A Comparative Thermoelastic Stress Analysis with Normal Composite Femurs [PDF]

Bioengineering
Proximal femoral fractures associated with osteoporosis are an important clinical problem, yet how bone quality independently influences stress distribution remains insufficiently understood.

A Thermoelastic Stress Analysis General Model: Study of the Influence of Biaxial Residual Stress on Aluminium and Titanium

Metals, 2019
All the studies on the thermoelastic behaviour of materials, including the revised higher order theory on the thermoelastic effect, are based on several assumptions that limit the application of such theory to the cases of isotropic materials in the ...

T-stress determination using thermoelastic stress analysis [PDF]

Journal of Strain Analysis for Engineering Design, 2008
T-stress and mixed-mode stress intensity factors have been determined experimentally using thermoelastic stress analysis and using a finite element method. Pure mode I, strong mixed-mode I and II, and interacting cracks have been used as the case studies. A new technique has been proposed to identify the crack tip from thermoelastic images. It has also
