In this investigation, a combined FEM simulation and experimental nanoindentation approach was taken to determine the mechanical behavior of single crystal copper incorporating the mesoplastic constitutive model. the mesoplastic constitutive model was implemented into Abaqus/Explicit user subroutine –VUMAT. Comparison of FEM and AFM images of the out-of-plane displacement from nanoindentation on a (100) single crystal copper at depth of 310 nm, both showing a four-fold symmetry. (Liu et al., 2005)
