Study of the Tool Geometry Influence in Indentation for the Analysis and Validation of the New Modular Upper Bound Technique

Applied Sciences, 2016
Focusing on incremental bulk metal forming processes, the indentation process is gaining interest as a fundamental part of these kinds of processes. This paper presents the analysis of the pressure obtained in indentation under the influence of different

A method for measuring the contact area in instrumented indentation testing by tip scanning probe microscopy imaging [PDF]

, 2014
The determination of the contact area is a key step to derive mechanical properties such as hardness or an elastic modulus by instrumented indentation testing. Two families of procedures are dedicated to extracting this area: on the one hand, post mortem

Indentation of ellipsoidal and cylindrical elastic shells [PDF]

, 2012
Thin shells are found in nature at scales ranging from viruses to hens’ eggs; the stiffness of such shells is essential for their function. We present the results of numerical simulations and theoretical analyses for the indentation of ellipsoidal and ...

Indentation of ultrathin elastic films and the emergence of asymptotic isometry

, 2015
We study the indentation of a thin elastic film floating at the surface of a liquid. We focus on the onset of radial wrinkles at a threshold indentation depth and the evolution of the wrinkle pattern as indentation progresses far beyond this threshold ...

Indentation of Commercial Pure Titanium Processed by Cold Rolling

Metals
In this work, the effects of plastic deformation on the indentation behaviors of commercial pure titanium alloy were investigated. Titanium experienced various kinds of deformation by cold rolling processes, and the indentation behaviors were measured ...

Stick-Slip Behaviour of a Viscoelastic Flat Sliding along a Rigid Indenter

Tribology Online, 2016
The sliding contact of soft material surface due to a rigid indenter is different from metal and some other polymers. A stick-slip motion is more frequently obtained than a smooth motion. By modeling the soft material as low damping viscoelastic material,

Nanometer-resolved mechanical properties around GaN crystal surface steps

Beilstein Journal of Nanotechnology, 2014
The mechanical properties of surfaces and nanostructures deviate from their bulk counterparts due to surface stress and reduced dimensionality. Experimental indentation-based techniques present the challenge of measuring these effects, while avoiding ...

Nanoelectromechanics of Piezoresponse Force Microscopy

, 2004
To achieve quantitative interpretation of Piezoresponse Force Microscopy (PFM), including resolution limits, tip bias- and strain-induced phenomena and spectroscopy, analytical representations for tip-induced electroelastic fields inside the material are
