An analysis method using polar coordinates for planar problems

摘要

摘要: 经典弹性力学教材中都是通过单元的几何变形来推导平面问题极坐标下的几何方程. 这里, 用解析法从直角坐标系下的几何方程推出极坐标下的几何方程.

Abstract: Geometry deformation of unit graphics is used to obtained polar coordinate geometry equations for planar problems in the classic elastic mechanic courses. Analysis method is introduced to derive polar coordinate geometry equations for planar problems from Cartesian coordinate’s geometry equations.
