摘要
本文建立了正交曲线坐标中的六结点三十自由度等参曲壳三角形单元,考虑横向剪切的影响。坐标和位移均采用二次插值,以三角形单元为过渡单元计算三通问题,数值结果表明它的有效性。
A curved isoparametric triangular shell element -with six nodes and a total of 30 freedoms is developed, which is represented in orthogonal curvilinear coordinates. The influence of transverse energy is involved. Quadratic interpolation is applied to coordinates and displacements. There is a successful application for curved triangular shell element serving as transition element to calculate the problem of intersection shell. Numerical results indicate effectiveness of the present conforming model.
