An improved multi-objective identification of Johnson–Cook material parameters
International Journal of Impact Engineering, 2009Abstract A weighted multi-objective identification strategy is presented for estimating Johnson–Cook material parameters often used in general purpose finite element models. The method is shown through illustrative examples for two different materials (Nitronic 33 super alloy and Ti–6Al–4V) using sets of data from quasi-static and split Hopkinson ...

Johnson-Cook Constitutive Equation for Titanium Alloy TC11
Key Engineering Materials, 2013Studying the dynamic properties of a material are an important method to understand the dynamic processes and deformation mechanism of material at different working conditions, particularly at high strain rate. The constitutive equation of a material has the highest significance to represent the mechanical properties, and is the principal research ...

Numerical solution of shear localization in Johnson–Cook materials
Mechanics of Materials, 2003Abstract To compute shear localization, a recently developed numerical scheme is adapted for application to certain types of materials described by a Johnson–Cook model. In the context of a slab geometry, the numerical scheme requires discretization only in the time variable to yield the stress and temperature in a shear band.

How To Identify Johnson-Cook Parameters From Machining Simulations
AIP Conference Proceedings, 2011The Johnson‐Cook material model is a robust material model which has demonstrated its usefulness in describing material behaviour over large ranges of strains, strain rates and temperatures. During machining the material in the shear zone undergoes strains of more than 200%, strain‐rates of the order of 106 per second or more and a temperature rise of ...

Determination of Johnson-Cook constitutive equation for Inconel 601
Journal of Mechanical Science and Technology, 2018Due to their superior thermal and mechanical properties, super alloys widely used in the aerospace industry have been well-documented in terms of AdvantEdge-based analysis of cutting characteristics rather than experimental methods. However, the well-known super alloy Inconel 601 does not have any database of its material properties in AdvantEdge ...

Determination of Johnson–Cook Plasticity Model Parameters for Inconel718
Journal of Materials Engineering and Performance, 2017In order to simulate foreign object damage (FOD) phenomenon in aircraft high-pressure compressor blades made of a nickel-based super-alloy, Johnson–Cook (J–C) plasticity model was used. For prediction of material’s plastic behavior at temperature of 400 °C (working temperature of the blades) in the range of strain rates associated with the FOD ...

Modified Johnson-Cook model for vehicle body crashworthiness simulation
International Journal of Vehicle Design, 1999Dynamic response prediction of vehicle bodies is important for vehicle crashworthiness evaluation. The dynamic behaviour of vehicle body materials is dependent on material strain rates. One of the typical high strain rate tensile tests is the split Hopkinson bar test.

Constitutive modelling of Al7075 using the Johnson–Cook model
Bulletin of Materials Science, 2019In this paper, hot compression behaviour of Al7075 in the temperature range of 573–723 K and the strain rate range of 0.001–0.1 $$\hbox {s}^{-1}$$ , based on standard requirements, was studied.
