一、概述实验应力分析方法种类很多,有机械方法测定,如用千分表,杠杆引伸仪等。光学方法测定,如用光测弹性力学;塗漆方法测定,电学方法测定;分格画綱法测定;X射线测定等方法。用电学方法测定应变是非电学量的电测法中的一种,而非电量的电测法是测量技术中一个极其广泛的部份。实际上包括对一切数量的测量,这些数量被用来鉴定各种物理现象及生产过程。现代测量技术发展上的特点是普通采用电学测量仪器来测定包括非电量在内的一切 First, an overview of many types of experimental stress analysis methods, mechanical methods of determination, such as using a dial gauge, lever extensometer and so on. Determination of optical methods, such as the use of optical elasticity test; Determination of paint methods, electrical determination; Sub-grid outline method of determination; X-ray determination methods. Electrical measurement of strain is a non-electrical measurement method, and non-electrical measurement method is an extremely broad part of the measurement technique. It actually includes measurements of all quantities, which are used to identify various physical phenomena and production processes. Modern measurement technology is characterized by the development of the general use of electrical measuring instruments to measure, including non-electricity, including everything
