电测应力分析法是测量结构及材料变形的应力分析方法之一。应变仪和应变计广泛用于测量材料的力学性能和结构的应力,是实验应力分析中的一种常备仪器。随着材料科学的发展,人工合成新材料的不断应用,要求有一种大量程的应变仪和应变计来满足这些新材料的测试要求。大量程应变计国内已有生产,而目前生产的应变仪,一般量程小,最大只能测到两
Electrical stress analysis method is to measure the deformation of the structure and material stress analysis method. Strain gauges and strain gauges are widely used to measure the mechanical properties of materials and structural stress, which is a standing instrument in experimental stress analysis. With the development of material science, the continuous application of new synthetic materials requires a large range of strain gauges and strain gauges to meet the testing requirements of these new materials. Large range of strain gauges have been produced in the country, and currently produced strain gauges, the general range of small, the maximum can only measure two
