【摘要】 材料力学能量法的教学一般安排在杆件受力变形、强度理论及压杆失稳之后，单独成为一个章节，与结构力学、弹性力学等后续课程紧密衔接，能量法的学习对于学生采用全新视角分析力学问题十分重要。该文阐述能量法经典讲授思路，包括应变能与加载顺序无关、功的互等定理、外力功/余功和应变能/余能的转换和虚位移原理及虚力原理四种推导方式。旨在，其一，聚合不同思维方式，帮助学生理解能量法知识体系，启发学生科学思维与创新精神；其二，分析不同讲授方法的特点及不同本科专业的适用性，以针对不同人才培养模式合理安排课程内容。更多还原

【Abstract】 Energy Methods in Material Mechanics is generally arranged after the stress and strain analysis in most material mechanics books. It is closely linked to courses of structural mechanics and elastic mechanics for undergraduate students. This paper summarizes four typical class teaching ways for the energy methods. A comprehensive review of the energy methods is first provided.Then, comparison of the different teaching ways and their applicability to different undergraduate majors are provided in order to arrange more suitable teaching contents.更多还原
