Fracture modes and acoustic emission characteristics of hydrogen-assisted cracking in high-strength low-alloy steel weldment
(The Brazilian Society of Mechanical Sciences, 1999)
Digital signal processing of acoustic emission signals using power spectral density and counts statistic applied to single-point dressing operation
(Inst Engineering Technology-iet, 2017-08-01)
Dressing is an important operation for the grinding process. Its goal is to recondition the wheel tool to re-establish its cutting characteristics, owing to the wear produced after successive passes. Monitoring systems ...
Natural and laser-induced cavitation in corn stems: On the mechanisms of acoustic emissions
(Instituto de Física de Líquidos y Sistemas Biológicos, 2012-05)
Water in plant xylem is often superheated, and therefore in a meta-stable state. Under<br />certain conditions, it may suddenly turn from the liquid to the vapor state. This cavitation<br />process produces acoustic ...
Classification of burn degrees in grinding by neural nets
(2008-12-01)
One of the problems found in the implementation of intelligent grinding process is the automatic detection of surface burn of the parts. Several systems of monitoring have been assessed by researchers in order to control ...
Acoustic Emission behavior of thermally damaged Self-Compacting High Strength Fiber Reinforced Concrete
(Elsevier, 2018-10)
This paper investigates the effect of high temperature on two different Self-Compacting (SC) cementitious composites. SC-High Strength (SCHSC) and Fiber-Reinforced Concrete (SCHSFRC) samples were tested in three-point ...
Prediction of leak flow rate in plastic water distribution pipes using vibro-acoustic measurements
(SAGE Publications Ltd, 2018)
© 2017, The Author(s) 2017. Leakage from water distribution systems is a worldwide issue with consequences including loss of revenue, health and environmental concerns. Leaks have typically been found through leak noise ...
The newborn pain cry: Descriptive acoustic spectrographic analysis
(Elsevier B.V., 2014)
Comparative analysis of acoustic emissions produced in abrupt and non-abrupt fracture processes in reinforced concrete walls
(IOP Publishing Ltd, 2023)
The determination of the eventual abrupt fracture of a reinforced concrete structure is of fundamental importance to estimate and mitigate the possible damages caused by its failure; of particular importance are shear-type ...
Tool condition monitoring of aluminum oxide grinding wheel using AE and fuzzy model
(2018-04-01)
The grinding process is situated at the end of the machining chain, where geometric and dimensional characteristics and high-quality surface are required. The constant use of cutting tool (grinding wheel) causes loss of ...
Control of deviations and prediction of surface roughness from micro machining of THz waveguides using acoustic emission signals
(Academic Press-Elsevier, 2017)
By using acoustic emission (AE) it is possible to control deviations and surface quality during micro milling operations. The method of micro milling is used to manufacture a submillimetre waveguide where micro machining ...
