Simulating nanoindentation of thin Cu films using molecular dynamics and peridynamics

Ahadi, Aylin LU ; Hansson, Per LU and Melin, Solveig LU (2017) 8th International Conference on MATERIALS STRUCTURE & MICROMECHANICS OF FRACTURE In Solid State Phenomena 258 SSP. p.25-28
Abstract

Nanoindentation is a useful experimental method to characterize the micromechanical properties of materials. In this study molecular dynamics and peridynamics are used to simulate nanoindentation, with a spherical indenter targeting a thin single crystal Cu film, resting on an infinitely stiff substrate. The objective is to compare the results obtained from molecular dynamic simulations to those obtained using a peridynamic approach as regards the force-displacement curves and the deformation patterns after that the material parameters in the peridynamic model have been fitted to the force displacement curve from the molecular dynamic simulation.
