| Abstract | At a fundamental level, the thermo-mechanical response of metals in dynamic deformation processes such as machining is governed by dislocation processes and associated microstructure evolution. However, the most commonly used material constitutive models in machining are phenomenological (e.g. Johnson-Cook) or semi-phenomenological (e.g. Zerilli-Armstrong) and do not explicitly account for the dependence of material flow stress on dislocation and microstructure evolution processes in a unified manner. The fidelity of machining simulation models is dependent on the amount of micro-scale physics captured in the development of the material constitutive law, microstructure evolution law(s), and the unifying scheme integrating microstructure evolution into the constitutive law. This paper presents a unified material modeling approach that explicitly accounts for dislocation and microstructure evolution processes underlying the finite deformation process. The corresponding evolution laws are formulated and integrated into the constitutive model, which is derived from thermal activation theory and is an additive decomposition of athermal and thermal components of flow stress representing the effects of long-range and short-range obstacles to dislocation motion, respectively. The unified scheme is implemented as a user-defined subroutine in the AdvantEdge™ software (Third Wave Systems LLC) and used to simulate the orthogonal cutting of OFHC copper. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
