(PDF) Model-driven determination of Johnson-Cook material

The Johnson-Cook model is one of the simplest models to describe the material behavior in machining. The five J-C constants are related In this paper, an original approach was presented to identify the Johnson-Cook material constants (J-C constants).

backing plate is steel 42CrMo4. The elastic-plastic Johnson-Cook material law provides the dependence of the current yield stress on plastic strain, plastic strain rate and temperature, equation (3). The influence of temperature on the material thermal properties is not pronounced in the case of FSW, because their A thermomechanically motivated approach for rate, and temperature distributions from the thermomechanically enhanced model, Johnson-Cook material parameters are calibrated for orthogonal cutting tests of C38, 42CrMo4, and AA6082 materials where continuous chip formation prevails. A thermomechanically motivated approach for identification Oct 07, 2020 · By using stress, strain, strain rate, and temperature distributions from the thermomechanically enhanced model, Johnson-Cook material parameters are calibrated for orthogonal cutting tests of C38, 42CrMo4, and AA6082 materials where continuous chip formation prevails.

Five benchmark tests including one element tests, necking of a circular bar and 2D and 3D Taylor im-pact tests show the eciency and robustness of the proposed algorithm and conrm the improved Finite element simulations of the material loads and Jan 01, 2020 · According to the concept of Process Signatures proposed by Brinksmeier and others, in the present work the internal material loads and the resulting material modifications are analyzed for milling of quenched and tempered 42CrMo4 (AISI 4140). 3D finite element simulations were conducted utilizing the Coupled Eulerian-Lagrangian (CEL) method for Mechanical properties and dynamic constitutive model of Apr 05, 2017 · In a comparison of the JohnsonCook , BodnerPartom, and ZA models, Liang et al. found that the work-hardening rate of the ZA model, d/d, is independent of temperature and strain rate:(11) d d = C 5 n n 1. The ZA model for a BCC metal in its addition form is actually a constant work-hardening behavior model.
