Abstract:This paper instroduces a kind of Numerical Manifold Method based on the meshless idea.It creates the approximation function with moving least square method,deals with the boundary problem about displacement by applying punnishing function,sets up the discrete equation based on variational principle.At last,it proves that this method is practically applicable through numerical example.
Keywords:numerical manifold method  meshless method  moving least square method
