| Abstract: | Based on the 8-node isoparametric element of m edium/thick plate, this paper builds up a element by means of introducing generalized con forming condition of shear strain and displacement. Taking the element as plate part as well as taking plane element Q8 as membrane part, this paper builds up a new flat shell element. This new element is applicable to boty thick shell and thin shell. Numerical results show the new element has a good convergence and a high precision. |
