摘要
杆件变形涉及刚度和稳定性问题,梁变形问题作为其中典型代表在材料力学教学内容中占据较大比例。梁变形的求解不仅方法众多而且分布于教材的多个章节,本文讨论了不同方法的异同,意在辅助学生建立相关问题的知识“框架”,加深概念理解并开展思辨训练。
Structural deformation is related to stiffness and stability. Beam deformation, as a typical representative, occupies a large proportion in the teaching content of material mechanics. This paper discusses the similarities and differences of different methods in order to help students to establish the knowledge framework of related problems, deepen the concept understanding and carry out critical training.
