摘　　要：通过改进简单的功能原理,推导出用于计算线弹性结构位移的公式,形式与卡氏第二定理、单位力法完全相同.文中给出的具体授课内容表明,本文方法使材料力学能量法教学过程得以整合,且与结构力学图乘法自然衔接.大大简化推导过程的同时也有利于学生掌握理解.Based on improving work-energy principle, this paper derives the calculation formula for displacement of linearelastic structure. The form of formula is consistent with that of the castigliano＇s second theorem and unit force method. Lectures show that it makes energy method to integrate the teaching process. It is a natural and effective continuity of diagram multiplication method in structural mechanics. And the deduction process becomes easier and it is also helpftd for students to master and understanding

关 键 词：材料力学 线弹性结构 位移计算
