Re-defined DSGZ model has been proposed to effectively determine stress-strain relationship for thermo-plastic materials especially showing non-uniform deformation such as necking behavior during tensile test. Thanks to Rational Bézier curve, material constants of the proposed model can easily be identified from an experimental result, and adjustable parameters of the proposed model can also be determined by Simplex method. An example result with the proposed model is provided where fitted curve based on the proposed model successfully predicts experimental result.
