摘要: |
将文献[1]以二元二次B样条函数为基底,求解矩形薄板弯曲问题的二元B样条有限元的方法推广到用于求解平行四边形板弯曲问题.结果表明:该方法系数矩阵每行的非零元仅21个,相对于朱明权和Chui C.K.等的张量积型样条有限元方法,计算量与存贮量都大大节约. |

Abstract: |
A finite element method with bivariate B spline is given in[1] to solve a bending problem of rectangular boards based on the binary quadric B spline functions.we generalize the method to the case of parallelogram boards.It turns out that the method greatly reduces the computations and memory as comparied with the finite element method with splines of tensor product type of Zhu Mingquan and Chui C.K. etc. |
Key words: parallelogram boards bending problem finite element with bivariate B splines |
