Development and applications of thermoelastic stress analysis
Journal of Strain Analysis for Engineering Design, 1998The theory of thermoelastic stress analysis is reviewed and the implications of some theoretical developments are assessed. Available instrumentation is described and techniques available for separation of individual stress values are summarized. The scope of the technique is illustrated with reference to a number of applications covering crack-tip ...

Optica Acta: International Journal of Optics, 1982
After discussions on the need to measure the distribution of stress on the surface of a structure under load, and the connection between stress concentration, mechanical design and safety, a new technique for recording stress patterns called thermoelastic stress analysis (TSA) is described. For given material constants, the change in temperature on the

Review of Scientific Instruments, 2009
The application of thermoelastic stress analysis in composite materials is particularly complicated because of the anisotropy of the material, that determines the thermoelastic constant to be dependent on the direction of the fibers. A further difficulty depends on the constructive stratification of the material, whose mechanical properties vary with ...

Hybrid Thermoelastic Stress Analysis
Experimental Mechanics, 2014Solids, like a confined gas, experience an increase in temperature when compressively loaded and a temperature decrease when stressed in tension. While such stress-induced temperature changes at a point in a solid are related to a linear combination of the local changes in the normal stresses, it is often necessary to know the individual stress ...

Applications of thermoelastic stress analysis
Strain, 1986Recent advances in infra‐red technology have permitted SIRA Ltd to develop a highly sensitive instrument for full field experimental stress analysis. The calibration and performance of this instrument (SPATE) is being evaluated on a wide range of structural materials and engineering components at NEL, and techniques have been developed to extend the ...

THERMOELASTIC STRESS ANALYSIS BY MEANS OF A STANDARD THERMOCAMERA
Experimental Techniques, 2007Thermoelastic analysis is a recently developed full-field, no-contact technique based on detecting temperature changes induced by a dynamic load proportional to its amplitude and synchronous with load history.1 In fact, it is known that a specimen changes its temperature when subjected to cyclic stresses; if the strain is elastic, the temperature ...

Thermoelastic stress analysis of orthotropic composites
Experimental Mechanics, 1995The temperature variation in a cyclically loaded orthotropic composite is proportional to a linear combination of the changes in the normal stresses in the directions of material symmetry. An effective method is presented here to determine the individual stresses from measured thermoelastic data in a region adjacent to an arbitrarily shaped fraction ...
