确定温度分布和热应力的一种新的全息方法

An Improved Holographic Method for Determing Temperature Distribution and Thermal Stress

本文提出了一种能获得被测模型温度场和应力场的新方法,当一个二维光弹性模型受热载荷时,用这种方法能同时在两幅全息图上记录三个信息,从而使温度场与应力场的分离成为可能。

A new method for finiding temperature and stress field is proposed. In this method, three kinds of information could be recorded in two holograms at the same time if a two-dimensional photoclastic model is subjected to thermalloading. As a result, it is possible to separate the temperature field from the stress field.
