Computational approach using Johnson–Cook model on dual phase steel
Computational Materials Science, 2012In this research, two different hypo-eutectoid steels with different carbon content and alloying elements were made into samples with dual phase ferrite martensite microstructure. Their morphology and the mechanical properties were then compared. Computational model varying the ferrite percentage was also proposed.

JOHNSON-COOK FAILURE MODEL FOR ADDITIVELY MANUFACTURED 304L STAINLESS STEEL PARTS
2023Laser powder bed fusion (LPBF) process is a type of additive manufacturing technique which uses a powder bed to form complex metal parts in a layer-by-layer process. This study aims to understand the damage initiation in the parts manufactured by LPBF process using 304L stainless steel powder, which is widely used in numerous applications.

Constitutive Modeling of 2024 Aluminum Alloy Based on the Johnson–Cook Model
Transactions of the Indian Institute of Metals, 2019In this paper, hot compression behavior of Al2024 in the temperatures range of 573–723 K and strain rate range of 0.001–0.6 s−1 was studied based on standard tests. The prediction of flow stress was performed using constitutive equations based on the basic and modified Johnson–Cook model, and the accuracy of the proposed models was estimated by ...

Investigation of tensile Johnson-Cook model parameters for Nimonic 80A superalloy
Journal of Alloys and Compounds, 2019Abstract Developing high temperature technology increases the need for high temperature resistant materials. Nimonic 80A alloy is generally preferred due to its high creep resistance, oxidation resistance and high resistance to high temperature corrosion.

The Prediction Model of Cutting Forces Based on Johnson-Cook’s Flow Stress Model
Key Engineering Materials, 2008Thin-walled parts with complex configurations are extensively used in aerospace and precise instrument industry. However, because of low stiffness, cutting forces, clamping forces and residual stresses in cutting have been the main factors influenced on machining accuracy of thin-walled parts.

Johnson - Cook Strength Models for Mild and DP 590 Steels
AIP Conference Proceedings, 2006Automotive steels, Mild and Dual Phase590 (DP590) are characterized in tension at room temperature, using the quasi‐static and split Hopkinson bar techniques at various strain rates ranging from ∼10−3/s to ∼1800/s. Tension stress‐strain data for both the steels are analyzed to determine the Johnson‐Cook Strength model constants, J‐C strength model ...

Johnson Cook Material Model and Simulation Experiment of Aluminum Alloy 6005A
Advanced Materials Research, 2012The true stress-strain curve of aluminum alloy 6005A is attained by quasi-static compression experiments, and Johnson Cook material model parameters of aluminum alloy 6005A is determined by using least-squares fitting. The aluminum alloy 6005A finite element model of the oblique cutting process is established in ABAQUS software, and verified by the ...

Johnson-Cook Strength Model Constants for VascoMax 300 and 1080 Steels
AIP Conference Proceedings, 2006High strength steels, VascoMax 300 and 1080, are characterized under tension at strain rates of ∼1/s, ∼500/s, ∼1000/s, and ∼1500/s and at high temperatures using the quasi‐static and split Hopkinson bar techniques. The data on 1080 steel exhibited a typical strain hardening response, whereas Vasco‐Max 300 steel showed diminishing flow stress beyond ...
