| 中文摘要: |
| 本文提出了一种新的弹性与弹塑性问题的对称耦合解法。根据分区广义变分原理,直接导出问题的求解方程式。通过典型算例,验证了该方法的有效性,本文建议的方法与超单元形式的耦合法相比,在理论上比较直接,在计算上更为经济。 |
| 英文摘要: |
| This paper presents a new symmetric coupling approach of BEM and FEM of elastic and elasto-plastic problems. Based on the sub-region generalized variational principle, the solving equations of the problem are derived directly. The validity of the proposed method is demonstrated by typical examples. In comparison with the super-element method, the new approach has the advantages of being more straight in the theory and more economical in computation. |
