18.2.7 Johnson-Cook plasticity

where are failure parameters measured at or below the transition temperature, , and is the reference strain rate. You provide the values of when you define the Johnson-Cook dynamic failure model. When this failure criterion is met, the deviatoric stress components are set to zero and remain zero for the rest of the analysis.

Determination of JohnsonCook Material Parameters for

Nov 17, 2020 · In this paper, JohnsonCook flow stress and JohnsonCook failure models were adapted to predict the material behavior of armour steel. The material parameters for JC flow stress model were determined through experiments for varying strain rate from 10 4 to 1550 s 1 and temperature from 25 to 600 °C. The damage parameters of JC failure model were determined Experimental Investigations of Material Models for Ti predicted by the Johnson-Cook Material Model (Using the New Material Parameters) with Experimental Data. Calculations and Data were taken at a Strain of .04.

The titanium parameters, obtained from simulations of split Hopkinson bar tensile tests, were successfully used to simulate blade fragment impact tests on 0.602, 0.250, and 0.737 thick titanium targets. Johnson Cook Failure ParametersThe Johnson-Cook shear failure model can be used in conjunction with the Johnson-Cook plasticity model to define shear failure of the material (see Dynamic failure models, Section 11.2.8). The Johnson-Cook shear failure model is based on the value of the equivalent plastic strain at element integration points; failure is assumed to occur
