Validation of the Tabulated Johnson-Cook Model for a Dynamic Compression Simulation

Applied Mechanics and Materials, 2015
MAT224 is a tabulated version of the Johnson-Cook model in LS-DYNA. Compared with the original Johnson-Cook material, MAT224 was developed to simulate the dynamic response of a material by just defining the effective stress as a function of effective plastic strain at different strain rates and temperatures, thus avoiding the tedious parameter fitting ...

Johnson - Cook Strength Models for Mild and DP 590 Steels

AIP Conference Proceedings, 2006
Automotive 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 ...

Manufacture and Preparation of Test Specimens for Johnson-Cook Material Characterization

2013
Abstract : As a revision to Contract no. W56HZV-05-0721 (WD-FH-0004), this task was added to the current project for the purpose of performing material characterizations and developing Johnson-Cook (J-C) strength and damage constants of friction stir welded (FSW) ballistic joints.
