Influence of the crystallographic orientation and thickness of thin copper coatings during nanoindentation
(2015) In Engineering Fracture Mechanics 150. p.143-152- Abstract
- The structure of interest consists of a nanometer thin copper coating, resting on a stiffer substrate. The elastic and plastic properties of the coating are investigated for three crystallographic orientations and two coating thicknesses using nanoindentation simulated by molecular dynamics. The force-displacement curve, the atomic rearrangement, the stresses and the lattice disorder are monitored during indentation to determine and describe the occurrence and formation of pop-ins and pop-outs during loading. It was found that the crystallographic orientation strongly influenced both the stiffness, load for pop-in formation, the resulting deformation and the stress beneath the indenter.
