Nonlinear acoustic characterization of heterogeneous plasticity in bent aluminium samples
(Elsevier Ltd, 2023-03-14)
Knowledge of the state of plastic deformation in metallic structures is vital to prevent failure. This is why non-destructive acoustic tests based on the measurement of first order elastic constants have been developed and ...
Caracterização de vidro para fins forenses utilizando fluorescência de raios X por reflexão total e técnicas espectroscópicas vibracionais
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2023-04-25)
In this work, simple and fast analytical methods were developed and/or evaluated, using minimal sample preparation for the characterization of glass for forensic purposes, using total reflection X-ray fluorescence (TXRF), ...
Glass Difractive Optical Elements (DOEs) with complex modulation DLC thin film coated
(ABM, ABC, ABPol, 2008)
We developed a complex (amplitude and phase) modulation Diffractive Optical Element (DOE) with four phase levels, which is based in a glass substrate coated with DLC (Diamond Like Carbon) thin film as the amplitude modulator. ...
High performance concrete applied to storage system buildings at low temperatures
(ABM, ABC, ABPol, 2008)
According to some estimates, world's population growth is expected about 50% over the next 50 years. Thus, one of the greatest challenges faced by Engineering is to find effective options to food storage and conservation. ...
Application of dendrogeomorphology on the study of soil sediment deposition in the stems of Guarea guidonea trees in a disturbed riparian forest in Goias state, Brazil
(IPEF-INST PESQUISAS ESTUDOS FLORESTAISPIRACICABA, 2012-03)
The sediments resulting of natural or anthropic erosion are deposited on the soil surface and around the trunks of trees occurring in riparian forests. For assessment of the erosion, tree-rings of roots and stems were ...
Lamb mode diversity imaging fornon-destructivetesting of plate-likestructures
(London, 2014-02-24)
Several Lamb wave modes can be coupled to a particular structure, depending on its geometry and transducer used to generate the guided waves. Each Lamb mode interacts in a particular form with different types of defects, ...
NDT flaw mapping of steel surfaces by continuous magnetic Barkhausen noise: Volumetric flaw detection case
(ELSEVIER SCI LTD, 2009)
This paper reports the use of a non-destructive, continuous magnetic Barkhausen noise (CMBN) technique to investigate the size and thickness of volumetric defects, in a 1070 steel. The magnetic behavior of the used probe ...
Low energy ion scattering in He/HOPG system
(Elsevier Science, 2008-02)
Low energy ion scattering (LEIS) is a unique tool in surface analysis, since it provides the atomic composition of the outer atomic layer, and time of flight ion scattering (TOF) is a non-destructive method of analysis ...
Ultrasonic Lamb waves detection using an unstabilized optical interferometer with uncalibrated phase shifts
(Taylor & Francis, 2014-11)
We present an experimental and post-processing scheme that allows ultrasound surface wave detection by means of an unstabilized homodyne interferometric technique. We register interference signals for a set of uncalibrated ...
