[ 1 ] - Exponential-type Constitutive Equation in Order to Use in Modeling the Warm Deformation of a Eutectoid Steel

The main contribution of the present work is to investigate the capability of exponential-type constitutive equationto model the warm deformation flow curves of a eutectoid steel in the temperature range of 620-770 °C andat the strain rates in the range of 0.01-10 s-1 conducted on a Gleeble-1500 thermomechanical simulator. Warmdeformation in this temperature range f...

[ 2 ] - Genetic Algorithm-based Optimization Procedures to Find the Constants of Johnson-Cook Constitutive Equation

Johnson-Cook constitutive equation is one of the most famous constitutive equations that have ever been developed to model the hot deformation flow curves of different materials. This equation is a predefined model in the traditional finite element codes to describe the material behavior in applications such as simulating the manufacturing processes. In this work, two different genetic algorith...
