摘要 通过引进结点刚体转角,提出两个具有平面内旋转自由度的平面4结点扇形单元,数值计算表明这两种单元具有很高的计算精度,为具有圆形边界的结构有限元分析提供了有效实用的单元。 By introducing vertex rigid rotation as DOF , two plane sector elements are presented. Numerical results demonstrate that very good accuracy is achieved and they are the practical elements to analyze the structures with circular bnundary .
