| Abstract: |
| By introducing the concept of asymptotic perturbation, a convergent boundary integral equation approach for calculating the higher-order derivatives at boundary in Kirchhoff plate bending problems is presented, which effectively solves the problem of so-called hyper-singular kernal functions appearing in such integral equations. Satisfactory numerical results are obtained by applying the technique to the calculation of curvature terms at plate boundary. |
