Nanoindentation is modelled on the computer by means of a simple two-dimensional discrete dislocation model in order to study the influence of the orientation of predefined slip bands on certain phenomena, which often occur during real indentation experiments, systematically. By assuming single slip
The effect of size on the mechanical behavior and the void growth rate in a voided single crystal was studied using two-dimensional discrete dislocation dynamics. The simulations were based on the methodology developed by Van der Giessen and Needleman [Van der Giessen E, Needleman A. Modell Simul Ma
