Nanomechanical and nanotribological properties of carbon-based thin films: A review
TL;DR: In this paper, a-C and hydrogenated amorphous carbon (a-C:H) films with a mixture of sp 2 and sp 3 bonding are compared to metal/amorphous carbon composite films.
Journal ArticleDOI
Simulation of Berkovich nanoindentation experiments on thin films using finite element method
TL;DR: In this article, the authors applied the finite element technique to study the very complex stress-strain field of thin hard coatings subjected to a nano-indentation process, and the results showed that the ABAQUS finite element software package is capable of reproducing the loading-unloading behavior of a nano indentation test.

Evaluating mechanical properties and crack resistance of CrN, CrTiN, CrAlN and CrTiAlN coatings by nanoindentation and scratch tests
Qianzhi Wang,Fei Zhou,Jiwang Yan +2 more
TL;DR: In this article, the microstructure, mechanical properties, fracture toughness and adhesive strength were investigated via X-ray diffraction (XRD), nanoindentation and micro-scratch tests.
Journal ArticleDOI
Three-dimensional numerical simulation of Vickers indentation tests
TL;DR: In this article, a specific finite element simulation software, HAFILM, was developed to simulate the ultramicrohardness tests and different mesh refinements were tested because of the dependence between the values of the mechanical properties and the size of the finite element mesh.

On the factors affecting the critical indenter penetration for measurement of coating hardness
Jinju Chen,Steve Bull +1 more
TL;DR: The nanoindentation test is the only viable approach to assess the properties of very thin coatings (see as discussed by the authors for a detailed description of the test and a detailed analysis).

Hardness measurements of thin films

TL;DR: In this paper, a simple technique is presented to obtain the characteristic microhardness values of surface coatings that are too thin for the values to be directly measured, using a physical model of film deformation during indentation.

A study of the mechanics of microindentation using finite elements
Tod A. Laursen,Juan C. Simo +1 more
TL;DR: In this paper, the authors used the finite element method to explore the mechanics of the microindentation process and provided a more critical examination of the amount of pileup or sink-in around the indenter in the fully loaded configuration, as well as the variation of the actual contact area during indenter withdrawal.
