一、概述近年来,测定应变场的云纹方法已经在我国各高校、研究单位以及部分生产单位迅速推广开来。一些工科院校已将云纹法列入基本测试方法教学大纲。但是进行云纹测量的基本元件密栅版还没有象电测测量的电阻片那样在我国有正式商品出售。国外出售的密栅版(以下称普通版)一是价格贵,二是质量低。为满足我国云纹方法快速发展的急需,针对普通栅版 I. Overview In recent years, the moire method for measuring the strain field has been rapidly popularized in China’s universities, research institutes and some production units. Some engineering colleges have included moire method in the basic test method syllabus. However, the basic components for the moiré measurement Mirrored plate has not yet measured as the electrical resistance of the film as in our country have a formal sale of goods. Misc was sold abroad (hereinafter referred to as the ordinary version) First, expensive, and second, low quality. In order to meet the urgent need of the rapid development of moire method in our country, aiming at the ordinary grid plate
