| A NEW ELEMENT FOR THIN PLATE OF BENDING WITH CURVILINEAR BOUNDARY—CURVILINEAR BOUNDARY QUADRILATERAL ELEMENT | |
| 作者姓名： | 钱伟长 王刚 |
| 摘 要： | This paper presents a curvilinear boundary quadrilateral element for the problem ofthin plate of bending with curvilinear boundary.A coordinate transformation of twodimensions is performed in the calculation of FEM.The introduction of an additionalstiffness matrix based on the generalized variational principles results in high accuracy andless computation time.The numerical results agree with the analytical solution very well. |
