APPLICATION OF REAL-TIME 3D-DIC METHOD IN TEACHING MATERIAL MECHANICS1)

  • Experimental teaching is a crucial part of education in science and engineering colleges. To improve students understanding of theoretical knowledge substantially, it is of great significance in applying modern optical mechanics methods in experimental teaching. As two examples, this article carried out aluminum alloy tensile experiment and three-point bending experiment of beam model, using self-developed real-time three-dimensional (3D) digital image related methods to display teaching contents. This method can measure the three-dimensional shape and deformation of the surface of an object in real time, and intuitively reveal the deformation laws and mechanics principles in material mechanics. Practice shows that classroom presentations mobilize students' enthusiasm, and the combination of theory and experiment increase students' ability in analyzing problems. Compared with traditional electrical measurement methods, it has incomparable advantages.
