%X Based on the three-point bending experiment,the specimen loading - displacement curve is obtained through the digital speckle correlation method.According to the displacement of the specimen,the elastic modulus of PMMA is obtained.It is shown that the elastic modulus obtained in experiment is objective and authentic.It is an efficient and feasible method to measure elastic modulus for PMMA and other polymers.
