Constitutive model of 42CrMo steel under a wide range of ...

Jan 02, 2017 · The macroscopic strain rate was considered in the evolution of the shear rate, and temperature rise was considered in the hardening rules. The model was confirmed to describe the quasi-static and dynamic mechanical behavior of the 42CrMo steel very well, especially the effects of strain hardening and thermal softening.

A Characterization for the Constitutive Relationships of ...

A number of constitutive models have been proposed to describe hot deformation behavior. Generally, these models are mainly divided into three categories phenomenological 5,6, physical-based constitutive model7,8 and artificial neural network model9. The phenomenological models consist of some mathematical functions which lack of physical background.

Constitutive relationship is a mathematical representation for describing the correlation between flow stress, strain, strain rate and temperature in a wide range of working conditions [5, 6]. Many researchers have attempted to develop constitutive equations from the experimental data to accurately describe the thermal deformation behavior of materials [ 7 – 11 ].

This was attributed to the inaccurate assumptions used in developing these models. In contrast, the VA model most effectively describes the flow stress and strain hardening in which very good predictions are observed for the constitutive behavior of high strength steel over a wide range of strains, strain rates, and temperatures.

Nevertheless, the JC constitutive model in its original form is often unable to guarantee enough accuracy on the flow stress prediction of materials. Therefore, it is a necessity to modify the conventional JC model to express the flow response with sufficient prediction precision over a wide range of temperatures and strain rates.
