Abstract:

This work was concerned with the Arlequin theory and its application to numerical simulation of structures. Various available multi-scale simulation methods of large-scale structures were overviewed. The basic concept of the Arlequin method and its continuous and discrete formulations for linear elastic problems were introduced. The selection of key parameters such as the weight functions and coupling operators as well as the scaling parameter of H1 coupling operator was suggested. The program based on Matlab software was developed and the multiscale analysis of a onedimensional rod and a two-dimensional beam was conducted. The numerical results verify the feasibility of the Arlequinmultiscale analysis with the same precision and higher efficiency. The stress in a V-notched plate was also investigated by implementing the Arlequin method into ABAQUS software, indicating the potential in the multi-scale study of large-scale structures.
