Based on traditional structural mechanics experiments, the current status of experiment teaching is analyzed. Furthermore, the necessity and feasibility of visualized experiment teaching course in structural mechanics is elucidated. To overcome the shortcomings of the existing teaching experiments and enable students to understand the concept of mechanics better, we try to apply DIC full-field strain measurement system to mechanics experiments teaching, replacing the traditional strain gauge and displacement gauge measurement. Through relevant experiments, the feasibility of visualization of structural mechanics expartment is verified and then a suitable experimental teaching scheme of structural mechanics is discussed.
