Numerical modelling of micro-machining of f.c.c. single crystal: influence of strain gradients
journal contribution
posted on 2017-06-30, 10:02 authored by Murat Demiral, Anish RoyAnish Roy, Tamer El Sayed, Vadim SilberschmidtVadim SilberschmidtA micro-machining process becomes increasingly important with the continuous miniaturization of components used in various fields from military to civilian applications. To characterise underlying micromechanics, a 3D finite-element model of orthogonal micro-machining of f.c.c. single crystal copper was developed. The model was implemented in a commercial software ABAQUS/Explicit employing a user-defined subroutine VUMAT. Strain-gradient crystal-plasticity and conventional crystal-plasticity theories were used to demonstrate the influence of pre-existing and evolved strain gradients on the cutting process for different combinations of crystal orientations and cutting directions.
