| 摘要: |
| 利用5次插值样条函数,将二阶Hermite梁单元加以改进,使其具有明确含义的结点参数广义化,从而使高阶单元能够应用于曲率不连续的变截面梁、板、壳等结构中。算例表明这种高阶广义参数单元不仅保持了5次Hermite单元及5次样条函数的优点,并且克服了其不能直接应用于曲率不连续的变截面结构中的缺点。 |

| Abstract: |
| The quintic B-spline functions were used to adapt the common hermite beam element into a new kind of generalized quintic element.This new kind of high-order element has generalized nodal coefficients,and can be used to compute the beams whose curvity are uncontinuous.Examples in this paper show that the high-order generalized element keeps both the merits of quintic hermite elements and spline functins. |
