In this paper, an approach based on the objective speckles field to measure the elastic modulus of solid material with
three-points bending method is presented. The speckle images of the loading force rod under different loading are
recorded and performed Fast Fourier Transformation (FFT), the deflection of the specimen can be obtained. The Young's
modulus of the specimen calculated agrees well with that of stretch approach. The approach presented in this paper has
advantage of simplicity, noncontact and high accuracy.
