Briefing: Non-destructive evaluation and contrasts of concrete overheated and abruptly cooled
(Thomas Telford Publishing, 2017-09)
Concrete structures can suffer different pathologies, one of which may be due to exposure to high temperatures. In this briefing paper, different concrete types were exposed to high temperatures. To simulate fire extinction, ...
Effect of fiber orientation on the shear behavior of glass fiber/epoxy composites
(Elsevier B.V., 2015-01-01)
This paper deals with the study of the influence of the lay-up configuration on interlaminar and in-plane shear properties of glass fiber reinforced epoxy composites. The following laminates were produced by resin transfer ...
Lamb wave inspection using piezoelectric diaphragms: An initial feasibility study
(2021-11-01)
Lamb wave-based inspection has been extensively investigated and reported in the literature as a non-destructive technique in structural health monitoring and other applications. The generation and reception of Lamb waves ...
Non-destructive evaluation tool for monitoring and detection of structural damage by using neural network
(2000-01-01)
This work studies the capability of generalization of Neural Network using vibration based measurement data aiming at operating condition and health monitoring of mechanical systems. The procedure uses the backpropagation ...
Non-invasive quantification of vitamin C, citric acid, and sugar in ‘Valência’ oranges using infrared spectroscopies
(2020-01-01)
Near (NIR) and mid (MIR) infrared spectroscopies have been studied as potential methods for non-destructive analyses of the fresh fruits quality. In this study, vitamin C, citric acid, total and reducing sugar content in ...
Relation between magnetic Barkhausen noise and hardness for jominy quench tests in SAE 4140 and 6150 steels
(New York, 2013-01-30)
he nondestructive Magnetic Barkhausen Noise (MBN) technique was applied for the evaluation of SAE 4140 and SAE 6150 steels after a Jominy end-quench test. Microstructures were also characterized by SEM (Scanning Electron ...
Use of clearance rate in Choromytilus chorus (Bivalvia: Mytilidae) as a non-destructive biomarker of aquatic pollution
(Sociedad de Biología de Chile, 2003)
Evaluation of a Non-Destructive Impact Sensor to Determine On-Line Fruit Firmness
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Magnetic non-destructive evaluation of ruptures of tensile armor in oil risers
(IOP PUBLISHING LTDBRISTOL, 2012)
Risers are flexible multilayered pipes formed by an inner flexible metal structure surrounded by polymer layers and spiral wound steel ligaments, also known as armor wires. Since these risers are used to link subsea pipelines ...
Evaluation of weather influence on mechanical and viscoelastic properties of polyetherimide/carbon fiber composites
(2013-06-01)
In order to investigate how environmental degradation affects the mechanical and thermal performance of polyetherimide/carbon fiber laminates, in this work different weathering were conducted. Additionally, dynamic mechanical ...
