项目摘要

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.
拟议研究的目的是扩展热像仪的能力,从测量数据中分析单个应力。热像仪是一种红外记录,记录固体中伴随着应力变化的微小温度变化。该方法是一种非接触式、灵敏、方便的方法,与常用的应力分析方法相比具有许多优点。然而,目前热像图只是定性的,提供的是主应力之和的信息,而不是单个应力的信息。在拟议的研究中,将探索分析和计算技术的组合来分离应力分量。这项研究是基础性和探索性的,但它的成功完成将在无损应力分析中具有重要的实际应用价值。
