Exploratory Investigation to Determine Individual Stresses Thermographically

所提出的研究的目的是扩展能力 通过温度记录法来分析测量到的 数据 热成像是用红外线记录微小的温度变化 伴随着固体中的应力变化。 该方法是 非接触、灵敏、方便，具有许多优点， 用于应力分析的常用技术。 但目前 温度记录法只是定性的， 主应力的总和，而不是单个应力。 在 建议研究分析和计算相结合 将探索分离应力分量的技术。 本研究具有基础性和探索性，但其成功之处在于 完成将有一个重要的实际应用， 非破坏性应力分析

The purpose of the proposed research is to extend the capability of thermography to analyze individual stresses from the measured data. Thermography is infrared recording of small temperature changes that accompany stress changes in a solid. The approach is non-contacting, sensitive and expedient and has many advantages over prevailing techniques used for stress analysis. However, at present thermography is only qualitative and provides informaticn on the sum of principal stresses and not the individual stresses. In the proposed research a combination of analytical and computational techniques will be explored to separate the stress components. The research is fundamental and exploratory, but its successful completion will have a significant practical application in non-destructive stress analysis.
