摘要
本文提出了塔宝剪切干涉法测量应力和与应力和梯度的新方法,导出了光路的数学公式,并通过对径受压圆盘的实验与计算,证实了实验结果与理论值符合良好.
In this paper, a new method for measurement of stress sum and its gradient by Tallot shearing interferometry is proposed. The formula for optical system is derived. The experimental results of the circular disk loaded diametrically agree pretty well with theoretical analysis.
