Based on the basic characteristics of the material mechanics course, the actual situation during the teaching process, and the relationship between education and scientific research, we applied the achievements of scientific research in teaching to help students to understand the elementary knowledge, foster their creativity, develope their basic research capacity, and expand their thinking extension and depth. We took a part of composites materials content as a case study, introduced numerical test method in it, built a numerical model, and combined the numerical test results with the classroom teaching to improve the teaching efficiency.
