“…Material rupture was considered using Jonson-Cook rupture model [11]. Finite element breaking occurs when D=1: The parameters taken into consideration in this study materials were observed in [12][13][14][15]. The impact of the speed of deformation was not considered in this study.…”

“…For example, Ulacia et al and Bhattacharya et al used modified JC models to predict the flow behavior of an aAZ31 magnesium alloy at an elevated temperature [6,7]. Meanwhile, several calibration strategies for the JC model were proposed and clearly discussed by Gambirasio et al [8]. Basing on dislocation mechanics, Zerilli et al proposed the Zerilli-Armstrong (ZA) model with two different forms to separately describe the constitutive relationships of the fcc structure and bcc structure [9].…”

The work presents a full mathematical description of the stress-strain compression curves in a wide range of strain rates and deformation temperatures for Armco-type pure iron. The constructed models are based on a dislocation structure evolution equation (in the case of dynamic recovery (DRV)) and Avrami kinetic-based model (in the case of dynamic recrystallization (DRX)). The fractional softening model is modified as: X = ( σ 2 − σ r 2 ) / ( σ d s 2 − σ r 2 ) considering the strain hardening of un-recrystallized regions. The Avrami kinetic equation is modified and used to describe the DRX process considering the strain rate and temperature. The relations between the Avrami constant k ∗ , time exponent n ∗ , strain rate ε ˙ , temperature T and Z parameter are discussed. The yield stress σ y , saturation stress σ r s , steady stress σ d s and critical strain ε c are expressed as the functions of the Z parameter. A constitutive model is constructed based on the strain-hardening model, fractional softening model and modified Avrami kinetic equation. The DRV and DRX characters of Armco-type pure iron are clearly presented in these flow stress curves determined by the model.

“…Over the years, the most popular application of the Taylor impact test has been the evaluation of the performance under high strain loading of constitutive material models . However, lately, it is being used as a data source to optimize some of the material parameters for diverse material models . For example, Julien et al determined the constitutive behavior, including flow stress function, damage and fracture, of brass from Taylor tests.…”

Identification of material constitutive parameters is critical for accurate representation of the mechanical behavior of materials at high strain rates. However, customary characterization procedures based on curve fitting of stress-strain curves, in some cases, are not accurate when the mechanical response exhibits strain rate dependency. In this paper, an inverse characterization technique based on the Taylor impact test is proposed. The technique uses a data reduction operator based on line moments and genetic algorithm optimization to determine the optimum constitutive parameters. Material parameters for a low carbon steel associated with the Plastic Kinematic model were determined using the proposed method.
