摘要
在求解弹性力学空间问题时 ,常用的坐标系是直角坐标、柱坐标和球坐标等 ,但对于环形管状的物体 ,用上述几种坐标求解均感不便 .为此提出一种环坐标 ,并研究在环坐标下的平衡微分方程、几何方程以及本构方程 .
When solving space question of elasticity,rectangular cartesian coodinates,cylindrical coodinates and spherical coodinates are often used.But they are not convenient to ring-tubular body.In this paper a ring coodinates was developed,and differrential equations of equilibrium,geometrical equations and constitutive equations in the ring coodinates were derived.
