  • Based on the meshless natural element method, a new algorithm was proposed to solve 2D viscoelastic problems. According to the elasticviscoelastic correspondence principle and the Laplace transform technique, the viscoelastic problem was transformed into an elastic problem in the Laplace space and then the basic formula of the natural element method for the analysis of viscoelastic problems were derived. As a recently developed meshless method, the natural element method (NEM) is essentially a Galerkin method based on natural neighbour interpolation. Compared to most other meshless methods, the shape function employed in the NEM has interpolation property and its support domain is anisotropic. Some numerical examples verify the effectiveness of the developed method.
