Research Abstract

The overlaying mesh finite element method, which uses global and local mesh that overlies each other, is applied for 2 dimensional elastostatic problem and plate bending problem. The results are compared with the traditional zooming analysis, in which displacement or load boundary conditions obtained by global analysis are given to local analysis. It was shown that while the accuracy of zooming analysis greatly depends on the size of the global mesh, the overlying mesh analysis generally gives quite good results even when coarse mesh is used in global analysis. Also the method that repeat local and global analysis iteratively is proposed, which makes it possible to use general purpose FEM code in overlaying mesh method, and it was shown that using under relaxation the convergence speed increase.
