This work is concerned with the modeling of necking phenomenon in metallic tension members using a nonlinear theory of elasto-plastic rods with deformable cross-section. The study of the coupling between the axial deformation and the cross-section deformation is a basic step to understand the strain-softening and localization behaviors in metallic structures. A complete set of elasto-plastic constitutive equations is proposed. The study is restricted to quasi-static and isothermal processes.
