Nanoindentation of thin copper coatings

Hansson, Per LU and Jansson, M. (2014) 7th International Conference on Materials Structure and Micromechanics of Fracture (MSMF 7) In Materials Structure & Micromechanics of Fracture VII (Key Engineering Materials) 592-593. p.417-420
Abstract
The structure of interest is a thin, metallic coating of fcc copper, of thickness down to a few nanometers only, resting on a stiffer substrate. The elastic and plastic properties of the thin coating using nanoindentation under different geometrical features such as size of the indenter and coating thickness are determined. The force-displacement curve is monitored during indentation and the precise conditions for the occurrence of so called pop-ins during loading are investigated. To simulate the nanoindentation process, a molecular dynamics approach is used, where an infinitely stiff indenter is pushed into the coating under displacement control. The coating is modeled as a thin rectangular plate, with the bottom atom layers locked from... (More)
