Stresses can significantly influence the mechanical integrity of engineering structures. Motivated by prevalence of members containing cutouts, the objective of this paper is to demonstrate ability to stress analyse a finite, complicated‐shaped plate containing an asymmetrical, irregularly shaped hole. Combining the load‐induced temperature information with analytical and numerical tools provides the independent stresses full field, including on edges of the plate and adjacent to the top load. In addition to utilising real, rather than complex, variables, the technique smooths the recorded information, evaluates individual stresses, and requires neither differentiating the measured data nor knowing the elastic properties. Results are supported by those from a finite element analysis, force equilibrium, and strain gages.

包含不规则形状孔的任意几何形状的实验应力分析

应力会严重影响工程结构的机械完整性。受包含切口的构件的普遍性影响，本文的目的是证明能够对包含非对称，不规则形状孔的有限，复杂形状的板进行应力分析。将载荷引起的温度信息与分析和数值工具相结合，可提供独立的应力全场，包括板边缘和顶部载荷附近。除了利用真实而非复杂的变量外，该技术还可以使记录的信息变得平滑，评估各个应力，并且既不需要区分测量数据也不需要知道弹性。结果得到了有限元分析，力平衡和应变计的支持。
