The finite element formulation of the coupled analysis of plastic deformation and heat conduction is studied for the numerical analysis during the metal forming process at elevated temperatures. As an extension of previous studies, a method of estimating equivalent plastic strain during the steady-state forming process is proposed in the present study, which is applicable to both strain- and strain-rate-dependent materials. As an example of numerical calculation, the coupled heat and deformation analysis for an axisymmetric steady state dieless drawing is performed. The distribution of temperature, plastic strain-rate, equivalent plastic strain and the change of billet shape during dieless drawing are calculated. The obtained results are in good agreement with experimental data. The influence of the work-hardening exponent on deformation and the distribution of temperature is also discussed.
