The subloading surface model possesses the automatic controlling function to pull back the stress to the yield surface. However, this function is not concerned with the subyield state, i.e. the elastic to the plastic transitional state and thus the accurate solution cannot be obtained in the transitional state. Besides, the function is ineffective for large loading increments even in the yield state. In this article, the return-mapping in cutting-plane projection for the subloading surface model is formulated aiming at obtaining accurate solutions in a high efficiency in the whole loading state, i.e. the elastic-plastic transitional and the yield states. Then, the validity of the elastoplastic deformation analysis by the subloading surface analysis with the return-mapping and the consistent tangent modulus tensor is verified comparing with the analysis by the forward-Euler method.
