Abstract

A moiré method is described whereby time-average slope contours are obtained from vibrating plates. It has an advantage over deflection contouring methods in that only first-order differentiation of experimental data is needed for stress calculations.

摘要

本文描述了一种云纹法，通过该方法可从振动板获得时间平均斜率等值线。它比挠度等值线法具有优势，因为在应力计算中仅需对实验数据进行一阶微分。
