摘　　要：探讨了有限元数值模拟在材料力学性能课程理论与实验教学过程中的应用。利用有限元模拟分析了缺口的应力集中效应、压缩过程中摩擦系数的影响以及材料拉/压对称性对弯曲变形的影响等典型应用。实践证明:利用有限元模拟技术可加强学生对材料力学性能课程复杂概念和理论的掌握,提升学生的学习兴趣,培养学生的创新性思维,同时改善教学效果。Application of finite element simulation in the theory and experiment teaching of mechanical properties of materials are discussed.By using the finite element simulation,several teaching cases,including the stress concentration effect of the notch,the influence of the friction coefficient on the compression process and the influence of tension/compression symmetry on bending deformation,are discussed in this paper.Making full use of finite element simulation technology can help students master the complex concepts and theories in mechanical properties of materials course,enhance students'interest in learning,and develop students'innovative thinking,and improve teaching effects.
