Effects of elastic indenter deformation on spherical instrumented indentation tests: the reduced elastic modulus
(TAYLOR & FRANCIS LTD, 2011)
Although the Hertz theory is not applicable in the analysis of the indentation of elastic-plastic materials, it is common practice to incorporate the concept of indenter/specimen combined modulus to consider indenter ...
The reduced modulus in the analysis of sharp instrumented indentation tests
(CAMBRIDGE UNIV PRESSNEW YORK, 2012-08)
In the analysis of instrumented indentation data, it is common practice to incorporate the combined moduli of the indenter (E-i) and the specimen (E) in the so-called reduced modulus (E-r) to account for indenter deformation. ...
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 ...
Instrumented indentation testing of an epoxy adhesive used in automobile body assembling
(ELSEVIER SCI LTD, 2008)
Instrumented indentation has been used to investigate the mechanical properties of BETAMATE 1496 (R) Epoxy adhesive. The properties of the adhesive were analyzed by measuring its hardness and its Young`s modulus in samples ...
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 ...
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 ...
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 ...
Numerical analysis of different methods to calculate residual stresses in thin films based on instrumented indentation data
(CAMBRIDGE UNIV PRESSNEW YORK, 2012)
In this work, different methods to estimate the value of thin film residual stresses using instrumented indentation data were analyzed. This study considered procedures proposed in the literature, as well as a modification ...
