| Abstract: |
| In a new systematic methodology for two\|dimensional elasticity, a new dual differential matrix L is presented by the dual vectors over again sorted in the paper of Zhong Wanxie and a new orthogonal relationship is discovered for isotropic plane problems. The new orthogonal relationship is proved and the relation between the reciprocal theorems and the orthogonal relationship is studied for the isotropic plane problems. The new orthogonal relationship includes the orthogonal relationship in the paper of Zhong Wanxie for the isotropic plane problems. |
