Improving Mechanics Teaching with Computer Aided Technology: Development of Digital Materials Based on FEA

Traditional mechanics experiments in vocational colleges suffer from complex equipment, multiple steps, and inherent risks, resulting in suboptimal teaching quality. To address this challenge, this study proposes a solution to enhance mechanics education through the use of computer-aided technology. Specifically, we utilize Finite Element Analysis (FEA) to obtain digital materials such as Mises stress plots, displacement diagrams, and animations, with the aim of improving classroom teaching quality. A case study approach was employed, with a focus on a torsion experiment that carries certain risks. Two finite element models, solid and hollow shafts, were developed, and numerical calculations were performed to generate visual materials represented by colored plots. These visual materials were integrated into the existing curriculum. The teaching content was redesigned, and the instructional experiments were conducted in four classes. Following the conclusion of the experiments, an evaluation of the teaching approach was conducted through a combination of questionnaires and teacher-student discussions. The questionnaire results indicated that 90.96% of the students considered the instructional experiments successful, with 89.84% expressing approval of the visual materials. The teacher-student discussions revealed a positive attitude toward the application of new technologies. Students also suggested allowing more time for discussion and interaction in the classroom. In conclusion, the development of digital materials based on FEA provides a new avenue for innovation in mechanics experiment teaching, deserving further exploration.
