“三关系法”在扭转与弯曲分析中的应用

摘要

The paper introduces and interprets the“ three-relation method”,including the geometrical relationship of deformation,the stress-strain relationship and the statics relation,introduces the analysis method of the method in the torque and flexural loads,and indicates by adop-ting some examples,so as to provide some reference for its application in work and study.%对“三关系法”即变形几何关系、应力应变关系、静力学关系进行了名词阐释，介绍了“三关系法”在扭转与弯曲中的分析方法，并结合实例作了说明，有助于实际工作及学习的参考应用。
