This paper mainly analyzd the foundation knowledge of the Finite Element Mesh(FEM)Superposition Method and the mathematical model is derived by considering the global and local area of theproblem.Finally the stress concentration of the plate with circle holes are analyzed and compared with originalfinite element analysis results.It shows that the FEM superposition method has its application merits for themulti-scale analysis in engineering.
