A method of elastic-plastic stress analysis based on the combination (FEM+BFM) of finite element method (FEM) and body force method (BFM) is developed. FEM+BFM has the advantages of both method (FEM and BFM) and has many possible applications. The line elements of BFM are located along the interface between the outer elastic domain and the inner elastic-plastic domains which are composed with FEM elements. In the present study, the method is applied to solve the problems of an elliptical hole contained in an infinite plate under various combined remote stress (σ_<x∞>, σ_<y∞>, τ_<xy∞>). The stress and strain concentration, the extension of plastic zone and the applicability of Neuber's rule under various combined remote stress (σ_<x∞>, σ_<y∞>, τ_<xy∞>) are investigated in details.
