“…For example, Abushawashi et al modified the Rice-Tracey model by incorporating the strain rate impact on ductility in order to simulate serrated chip formation in steel AISI 1045 [27]. The Johnson-Cook damage model was widely applied to simulate serrated chip formation for different materials, for example, Inconel 718 by Singh et al and Sievert et al [28,29], titanium Ti-6Al-4V by Zhang et al [30], or AISI 1045 by Vaziri et al [31].

“…The application field of CDM theory is very extensive: the theory has been used to describe fatigue , creep , biomechanical problems , brittle or ductile fracture or fracture related to impact problems. In this paper, we focus on ductile damage for which there are a lot of damage models (a more detailed bibliographical study of macroscopic ductile damage models can be found in Jeunechamps ): let us cite for example Lemaitre's model , Goldthorpe's model , Geers’ model , Cochran and Banner's model , Bonora's model , Johnson‐Cook's model modified by Borvik and Langseth and Longere's , Omerspahic's and Zhu's anisotropic models.…”

SUMMARYThis paper aims at presenting a general consistent numerical formulation able to take into account, in a coupled way, strain rate, thermal and damage effects on the behavior of materials submitted to quasistatic or dynamic loading conditions in a large deformation context. The main features of this algorithmic treatment are as follows: A unified treatment for the analysis and implicit time integration of thermo‐elasto‐viscoplastic constitutive equations including damage that depends on the strain rate for dynamic loading conditions. This formalism enables us to use dynamic thermomechanically coupled damage laws in an implicit framework. An implicit framework developed for time integration of the equations of motion. An efficient staggered solution procedure has been elaborated and implemented so that the inertia and heat conduction effects can be properly treated. An operator split‐based implementation, accompanied by a unified method to analytically evaluate the consistent tangent operator for the (implicit) coupled damage–thermo‐elasto‐viscoplastic problem. The possibility to couple any hardening law, including rate‐dependent models, with any damage model that fits into the present framework.All the developments have been considered in the framework of an implicit finite element code adapted to large strain problems. The numerical model will be illustrated by several applications issued from the impact and metal‐forming domains. All these physical phenomena have been included into an oriented object finite element code (implemented at LTAS‐MN 2L, University of Liège, Belgium) named Metafor.Copyright © 2013 John Wiley & Sons, Ltd.

“…The development of a new damage model bases on an approach of Johnson and Cook[9]. This approach enables the damage prediction of ductile materials depending on the strain, the strain rate, the multiaxial state-of-stress and the temperature[10] and can be fitted to a specific material behaviour[11]. The accumulation of the incremental damage respects the exhaustion of the material formability.…”

The aim of the presented work was to define a criterion for the prediction of chip breakage in turning C45E+N (AISI 1045). The chip formation, the chip flow and the expansion of the chip due to collision with the periphery were modelled three-dimensionally using the Finite Element Method (FEM). The mechanical loads in the chip breakage zone were determined by comparing the modelled chip with high speed filming records of the real chip breakage cycle. Based on the calculated loads in the chip breakage zone a novel damage criterion based on an approach of Johnson and Cook was developed. This criterion enables the FEM-model to simulate chip breakage three-dimensionally for different tool geometries and varying cutting parameters. The enhanced FE model correlated well with high speed filming records of the chip flow and breakage as well as with the empirical determined cutting forces and chip temperatures.
