摘　　要：在适用于中厚板的八结点平板弯曲单元基础上 ,通过引入剪应变与位移的广义协调条件 ,建立起一种新型广义协调元 ,不仅保留了原单元适用于中厚板的特点 ,同时对薄板也给出了较精确的解 ,是一种厚板和薄板通用的新型广义协调元。Based on the 8-node element of medium/thick plate, this paper builds up a new type of generalized conforming element by means of introducing generalized conforming condition of shear strain and displacement. It not only retains the distinguishing feature of original element being applicable to medium/thick plate, but also gives a more precise result of thin plate. The new element is applicable to both thin and thick plates.
