Novel nanoindentation

Nanoindentation studies of materials

have recognized that surface contacts between materials are highly dependent on their mechanical properties1,2. Many different indentation and impression tests have been developed in an effort to measure such mechanical properties from a contact of known geometry. In the past two decades, however, a veritable revolution has occurred in indentation testing, owing to the development of new sensor...

Nanoindentation and incipient plasticity

This paper presents a large-scale atomic resolution simulation of nanoindentation into a thin aluminum film using the recently introduced quasicontinuum method. The purpose of the simulation is to study the initial stages of plastic deformation under the action of an indenter. Two different crystallographic orientations of the film and two different indenter geometries (a rectangular prism and ...

Nanoindentation of GaSe thin films

The structural and nanomechanical properties of GaSe thin films were investigated by means of X-ray diffraction (XRD) and nanoindentation techniques. The GaSe thin films were deposited on Si(111) substrates by pulsed laser deposition. XRD patterns reveal only the pure (000 l)-oriented reflections originating from the hexagonal GaSe phase and no trace of any impurity or additional phases. Nanoin...
