Effect of Pile-up in Nanoindentation of Micro and Nano crystalline Ni using FEM
Published online by Cambridge University Press: 01 February 2011
Abstract
A much better understanding of the contact mechanics can be obtained through finite element modeling. The experimentally determined tip shape function was included to reproduce the same contact area for a given contact depth as in the experiment. The fundamental material properties affecting pile-up are the ratio of the effective modulus to yield stress Eeff/Y and the work hardening rate.
