| Abstract: | The essential principle of fixed reproducing kernel function,moving reproducing kernel function and multiple fixed reproducing kernel function were stated,and the characters of three reproducing kernel function was analyzed.A meshless shapefunction was constructed by fixed reproducing kernel approximation,and solved the 2-D elastic mechanics problem by means of combining collocation.It proves that fixed reproducing kernel approximation has its particular advantages over other methods. |

| Keywords: | meshless method classical reproducing kernel function fixed reproducing kernel function collocation method |
