Coordinates of Principal Stresses for Elastic Plane Problem

Beijing Technical & Scientific Institute of Real Estate, Beijing 100021, P. R. China

摘要: 本文中讨论了弹性力学平面问题中由主轴应力曲线构成的正交曲线坐标系上的平衡方程,以及解的特性.同时,认为在弹性力学中还存在另一种构造解的方式,即可通过直接构造主轴应力正交网络获得主轴应力的解.

Abstract: In this paper, the equilibrium equations on orlhogonal curve coordinates made of curves of principal stresses are disscused and their properties in process of solution arepresented through a simple example. Therefore, it is deduced that there is another way to solve problems in elasticity, i.e., by assumption of orthogonal curves of principal stresses.
