摘要

A meshless methods with the goal of proposing Arlequin method based approach to solve viscoelastically damped sandwich model is proposed. The Arlequin method hence offers a framework to mix and glue different models with others. The possible discrepancy between the scales of the local and global models in the gluing zone is addressed with sufficient care. A continuous formulation of Arlequin method is described and the discrete version of the same is provided. A strategy for solving boundary conditions problems of viscoelastically damped sandwich beam model is then proposed and discussed and a numerical analysis for the Arlequin method based on the paradigm of domain decomposition is then proposed.
