| 摘 要： | 能量原理是解决弹塑性力学问题的一个重要途径，它是有限元法的基础。能量法应用于解决边值工程问题，显示了强大的优越性，极大程度上降低了对工程人员的数学能力要求。能量法并非一门新的横断学科，它渊源于物理学的功能定理。就能量法追本逐末，对之加以了另类阐述，目的在于希望有限元的学习者基于此能曲径通幽。

| Abstract: | The energy principle is an important approach for solving the problems of elastic-plastic mechanics as well as the basis of finite element method.The energy method is used for solving the margin value project problems.It has great advantages and can lower the requirement for engineers' mathematical ability to a great extent.It is not a new subject.It originates from the function principle of physics.This paper explains the energy method to help the learners of finite element method to understand it. |
