AFM topographies and dislocation slip traces are analysed after Berkovich nanoindentation at grain scale.

Pile-up distribution is strongly related to the crystallographic orientation and pile-up heights to the hardening modulus.

Numerical topographies in the size independent framework are in a fairly good agreement with the experimental observations.

Residual topography is very sensitive to the interaction matrix components of the single crystal plasticity model.
