The Discrete Least Square Method for Solving Plates with Variable Flexural-rigidity |
| |
| Abstract: | In this paper, the mixed method of discrete least square of MWR (Method of Weighted Residuals) is used for analyzing the bending strength of plates with variable flexural rigidity. The trial function selected is a double power series with unknown coeffcients. A method with continuity condition is proposed for analyzing the strength of plates with their flexural-rigidity varying discontinuously. The feasibility of the present method is demonstrated by the illustrative examples. |
