Abstract Scope |
Robust flow stress data is critical for accurate simulations of forgings in industrial applications. The Gleeble thermo-mechanical simulator is a commonly used piece of equipment for generating these data; however, the direct-resistance heating of the specimen introduces non-trivial thermal gradients within the sample that have a significant effect on the apparent flow stress. A technique will be described to quantitatively asses these gradients and their applicability in analyzing the data to develop such constitutive relationship for use in finite element models. |
