| 中文摘要: |
| 本文从部分协调的三角形薄板弯曲单元出发,并假设横向剪切应变在单元内线性变化,提出了一种考虑横向剪切变形的具有15个自由度的三角平板弯曲单元。该单元应用于薄板和中等厚度板分析均有较高的精度,计算效率高,可用于工程中具有复杂形状的薄板和中等厚度板结构的分析。 |
| 英文摘要: |
| In this paper, a triangular plate bending element considered transverse shear strain with 15 degrees of freedom has been developed based upon the Mindlin plate bending theory and using the partly consistent triangular element for thin plate bending. It is accuracy to deal with thin and moderately thick plate bending, and it is suitable for computing the plate bending problems with various shapes in practise. |
