This paper studies the method of measuring the elastic modulus of metal materials by the deflection method. The relationship between the deflection and the load and the elastic modulus of the metal cantilever beam is established, so that the elastic modulus of the cantilever beam is indirectly measured. The experiment requires that the deformation of the material is within the elastic range. Furthermore, the deflection method is adopted. Not only the method is simple and does not require expensive equipment, but also the average value of multiple sets of experimental results is used as the modulus of elasticity of the material during measurement, which ensures a certain accuracy.
