Abstract

The nanoscopic scale can be considered as a lower bound to the mesoscopic scale, for which the nonlocal elasticity and the lattice dynamics yield to the same motion equations and the total potential energy expressions. Nonlocal elasticity takes better into account the long-range effects of all points of the body on one point of the body. This paper presents a nonlocal approach of the elastic nanoindentation problem. Starting to the local representation, the nonlocal solution for contact pressures is developed, obtaining finite values in all points near the contact boundary, which accords better with the experimental results.
