Thermoelastic Stress Analysis System.
Abstract
Perhaps the single most important experimental requirement for the evaluation of the mechanical behavior of engineering materials is the determination of stress distributions under load. Experimental stress analysis is the basis for much of the engineering research and development presently conducted on solid materials. If loads are applied synamically as in the cases of cyclic (fatigue) loading or vibration loading, measuring the full field stress distribution is greatly complicated. And secondly, when damage develops in materials, strong local gradients in stress result which are critically important in the determination of the remaining strength or life of the component. Damage development in composite materials under cyclic and dynamic loading is an especially important example of this special need. In the last few years a new device has been developed that has demonstrated the capability to measure such stress fields using the principal of adiabatic temperature change pattern analysis.
