Abstract
This paper is devoted to the finite element modeling of the nanoindentation problem. The frictional contact between the Berkovitch indenter and the very thin elasto-plastic film is treated by the bi-potential method. The elasto-plastic constitutive equation is integrated by means of the radial return mapping algorithm and the consistent tangent operator is explicitly derived. Numerical results show the validity of the model.
