Finite Temperature Coupled Atomistic/Continuum Discrete Dislocation Dynamics Simulation of Nanoindentation

Abstract

Simulations of nanoindentation in a hexagonal aluminum single crystal are performed using a finite temperature coupled atomistic/continuum discrete dislocation (CADD) method. The method captures, at the same time, the atomistic mechanisms and the long-range effects without the computational cost of full atomistic simulations. The effects of several process variables are investigated, including system temperature. We discuss the results and the deformation mechanisms that occur during a series of indentation simulations.
