Abstract: This paper introduces the FEA software element method in Engineering Mechanics teaching as an auxiliary method.By the use of FEA methods,teachers could display the mechanical concepts directly with graphics and animates,and could promote the students grasp the concepts.It can improve the students' interest in learning by the reasonable classroom experiment.By adjusting the parameters in the FEA software,the students can carry out autonomous learning,and even the preliminary scientific research.The introduction of finite element method can improve classroom teaching efficiency of mechanical courses,facilitate students' understanding and study,and provide guarantee for follow-up study of students.
