摘要: |
根据平面问题条形传递函数方法理论, 提出了平面问题广义超级单元的概念, 并推导了其刚度矩阵和结点力矢量表达式, 从而将条形传递函数方法应用范围推广到任意几何形状的平面区域。 |

Abstract: |
Based on the theory of strip distributed transfer function method (SDTFM), a new element, called generalized super-element (GSE) is given for 2-D problems and its stiffness matrix and nodal force vector are derived. With the use of generalized super-element, the application of SDTFM is extended to the 2-D problems of arbitary geometrical boundary. |
Keywords: SDTFM, generalized super-element, 2-D problems |
