本文提出的回转壳二次样条混合型单元,可用于求解回转壳的线性和几何非线性问题,它有未知数少,精度高的优点;又能很好地描述壳体中的局部效应.算例证明了本文方法的有效性.
In this paper, the so-called mixed quadratic spline elements for revolution shells are introduced. They can be applied to solve linear and geometrically nonlinear problems of revolution shells and to calculate combination shells. This kind of elements pos
