Abstract

The thermomechanical elasto-plastic problems in hot forging of the porous metals are analyzed using the thermo-elasto-plastic finite element method. This finite element program has been formulated using the yield condition advanced by Lee and Kim and developed using the thermo-elasto-plastic time integration procedure. Thermomechanical responses and densification behaviors of the porous metals during hot forging are calcucated at various initial relative densities, strain rates and temperatures. The calculated results are in good agreement with experimental data.
