| Abstract: |
| It is difficult to settle essential boundary conditions in meshless method because the meshless approximation functions are not built by interpolation schemes. A new meshless method was presented based on weighted least-square form and ridge basis functions interpolation ( WLSR). WLSR is a pure meshless method only based on nodal information. The results of numerical examples applied to elastostatics are satisfying. |
