Abstract: In this talk, we will present different nucleation and interaction induced by nano indentation in face-centered cubic (FCC) metals, and how these dislocations activities lead to 1) different surface deformation profiles that can be observed and measured, and 2) size effects due to dislocation-grain boundary interactions.
