About this document
Hot Deformation Flow Stress Modeling by Andrew R is a document available to read on EtoBox.
The document discusses the modeling and prediction of flow stress during hot deformation under dynamic recrystallization (DRX) conditions for a stainless steel alloy. It evaluates various constitutive equations, highlighting the limitations of the Johnson-Cook equation and proposing a simplified approach that incorporates the hyperbolic sine law for better consistency with experimental data. The study concludes that the deformation activation energy should not be treated as a function of strain for accurate
