Atomic force microscopy nano-indentation for testing mechanical properties in thin films
(Elsevier, 2019-07)
We study the mechanical properties of Cu thin films on Si (100) by performing nano-indentation using an atomic force microscopy. Cu films with thickness of 0.3 μm, 1 μm and 2 μm were analyzed. Area profile studies let us ...
A critical reassessment of elastic unloading in sharp instrumented indentation experiments and the extraction of mechanical properties
(TAYLOR & FRANCIS LTD, 2011)
This work examines the extraction of mechanical properties from instrumented indentation P-h(s) curves via extensive three-dimensional finite element analyses for pyramidal tips in a wide range of solids under frictional ...
On the propagation of methodological uncertainties in Depth Sensing Indentation data analysis: A brief and critical review
(Pergamon-Elsevier Science Ltd, 2020-04)
A systematic and critical review about the propagation of uncertainties related to the Depth Sensing Indentation data analysis standard procedures and its effect on the estimation of Young´s modulus of materials is reported. ...
Effects of mechanical properties, residual stress and indenter tip geometry on instrumented indentation data in thin films
(ELSEVIER SCIENCE SA, 2010)
In this work, an axisymmetric two-dimensional finite element model was developed to simulate instrumented indentation testing of thin ceramic films deposited onto hard steel substrates. The level of film residual stress ...
Finite element and dimensional analysis algorithm for the prediction of mechanical properties of bulk materials and thin films
(ELSEVIER SCIENCE SA, 2010)
In this work, the applicability of a new algorithm for the estimation of mechanical properties from instrumented indentation data was studied for thin films. The applicability was analyzed with the aid of both three-dimensional ...
Análise numérica da indentação de materiais elastoplásticos

This work aims at performing a numerical analysis on the indentation of elastoplastic materials. The simulations are carried out using the commercial finite element code Abaqus, employing an axisymmetric model. An important ...
Nano-indentation of hybrid silica coatings on surgical grade stainless steel
(Elsevier Science Sa, 2008-01)
Hybrid silica-based coatings with tetraethoxysilane (TEOS), methyltrietoxysilane (MTES), hydroxyethyl-methacrylate (HEMA) and methacrylopropyl-trimethoxysilane (γMPS) as precursors, were employed to improve the performance ...
Indentation Parameter Combinations on the Failure in a Coated System
(International Journal of Engineering Research and Technology, 2020)
Micromechanical characterization of ferritic ductile cast iron by using instrumented indentation and atomic force microscopy
(John Wiley & Sons Inc, 2020-10)
The aim of this investigation is to characterize the mechanical properties at the microstructural level in ferritic ductile iron. The analysis involves microstructural characterization, nanoindentation testing, atomic force ...
