Analysis on Mechanical Properties of Materials in Using Resistance Straingauge Method

The resistance straingauge method is commonly used in the actual components of the stress analysis of the experimental method,because of its high sensitivity,small sensors and high adaptability.The testing way has became one of the most extensive and effective methods in the practical engineering.This paper introduces the composition and the working principle of the resistance straingauge method,analysing the method of attaching resistance straingauges and dealing with data.Whats more,it can provide some skills and theoretical principle to solve some questions in other materials,which is important to the application in practice.
