【Abstract】 This paper firstly constructs a new kernel function to be applied in obtaining meshless approximations. Then it classifies two different discontinuous mechanical fields, and gives the altered projects. At last, it compares this kernel function with some general ones through theory and examples to show it is better than others.更多还原
