摘要
平面应力(应变)转轴公式是材料力学应力(应变)分析部分的主要教学内容,尽管转轴公式基于特定的应力(应变)状态导出,但在后续的应用,包括例题与习题中的引用并没有限定于平面应力(应变)状态。为了澄清学生常见疑惑,本文使用简单的方式对该问题进行说明,供教师教学时参考。
The transformation equation for plane stress(strain) is the main teaching content of the stress(strain) analysis of the mechanics of materials. Although the transformation equation is derived based on the specific stress(strain) state, it is not limited to the plane stress(strain) state in various applications, including examples and exercises. In order to clarify students’ common doubts, this paper uses a simple method to explain the problem so as to provide reference for teaching.
