Abstract: In order to solve the problem of complex and time-consuming data processing in the traditional photoelastic experiment teaching, the new photoelastic experimental technology is applied in the teaching of experiment. After a brief introduction of the basic method of the technology, this paper focuses on its applications in teaching of experiment with examples. The applications of this technology not only make the measurement in the photoelastic experiment go from the qualitative judgment to the quantitative one, but also expand students' vision and cultivate their innovative thinking abilities.
