摘要
试用数值计算模拟光弹贴片实验,分析双折射贴片法厚度效应。通过数值分析提出,构件表面应力梯度和贴片厚度是影响厚度效应的主要因素。本文还给出了贴片厚度为1,2,3mm时的m_(th)值,并提出了建议采用的修正方法。
In this paper, the photoelastic coating experiment is simulated by using the numerical calculation, and the thickness effects are analysed in the birefringent coating method. Through the numerical analysis, it is posed that the structure surface stress gradient and the coating thickness are the principal factor that influence thickness effect. This paper gives the mth values when the coating thickness is 1, 2, 3 mm, and a revisory method is proposed.
