Demiral, Murat Roy, Anish Sayed, Tamer El Silberschmidt, Vadim Numerical modelling of micro-machining of f.c.c. single crystal: influence of strain gradients A 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. untagged;Mechanical Engineering not elsewhere classified;Condensed Matter Physics 2017-06-30
