Design and Practice of Comprehensive Experiments for High-temperature Mechanical Analysis of Metallic Materials

By using high-temperature material mechanics testing machine and three-dimensional full field strain measurement system, and integrating advanced scientific research technology into experimental teaching, a teaching type high-temperature static tensile test method was constructed, and a comprehensive experiment of high-temperature mechanical property analysis of metal materials was newly built. In this experiment, laser extensometer method and three-dimensional non-contact full field strain measurement method (3D-DIC method) were used to measure the high-temperature deformation, and the high-temperature tensile deformation was visualized from a single numerical output to the full field deformation. The experiment also set up an assessment mode combining independent assessment and team cooperation assessment, promoting the improvement of teaching quality with cutting-edge technology, and strengthening the cultivation of students’ innovation ability and scientific research ability. The experiment has entered the undergraduate innovative experiment and graduate mechanical experiment curriculum system, and has achieved good results.
