Revisiting the Common Practice of Sellars and Tegart’s Hyperbolic Sine Constitutive Model

The Sellars and Tegart’s hyperbolic sine constitutive model is widely practiced in describing stress–strain curves of metals hot deformation processes. acceptance this phenomenological owed to its versatility (working for a wide range stress values) simplicity (being only function strain, strain rate, temperature). common practices are revisited work, with few suggestions improve results. Moreover, it discussed that, the progress data-driven models, main reason using should be identify reliable activation energies, not curves. Furthermore, piece code (Hot Deformation Fitting Tool) has been created automate analysis various models.
