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 ...
Physical–mechanical behavior of concretes exposed to high temperatures and different cooling systems
(Wiley Blackwell Publishing, Inc, 2017-06)
Over their lifetime, concrete structures can suffer from different pathologies, one of them is exposure to high temperatures, which diminishes their load-bearing capacity. This study describes how different concrete types ...
Bending stiffness evaluation of Teca and Guajara lumber through tests of transverse and longitudinal vibration
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAOMARINGA, 2012)
The grading of structural lumber besides contributing for increasing the structure's safety, due to the reduction of the material variability, also allows its rational use. Due to the good correlation between strength and ...
Ultrasound, eddy current and magnetic Barkhausen noise as tools for sigma phase detection on a UNS S31803 duplex stainless steel
(ELSEVIER SCIENCE SA, 2010)
Sigma phase is a deleterious one which can be formed in duplex stainless steels during heat treatment or welding. Aiming to accompany this transformation, ferrite and sigma percentage and hardness were measured on samples ...
Non-destructive assessment of kiwifruit physico-chemical parameters to optimise the osmotic dehydration process: A study on FT-NIR spectroscopy
(Academic Press Inc Elsevier Science, 2016-02)
Non-destructive rapid method based on FT-NIR spectroscopy is assessed to predict the processing response of raw materials at different ripening stages. During osmotic dehydration (61.5% sucrose solution, 5 h) ripe and ...
Evaluation of the density distribution in MDF's using ultrasonic wave technique
(Ipef-inst Pesquisas Estudos FlorestaisPiracicabaBrasil, 2007)
Avaliação do módulo de elasticidade da madeira com uso de método não-destrutivo de vibração transversal
(Associação Brasileira de Engenharia Agrícola (SBEA), 2005-08-01)
Numerosas pesquisas têm estudado os métodos não-destrutivos de avaliação de materiais e sua aplicação àqueles de matrizes complexas, como é o caso da madeira. Um dos primeiros métodos não-destrutivos investigados para ...
Wood Density Estimation Using The Sclerometric Method

Lignocellulosic composites from brazilian giant bamboo (Guadua magna) Part 1: Properties of resin bonded particleboards
(Universidad del Bío-Bío, 2011)
Study of the influence of simultaneous variation of magnetic material microstructural features on domain wall dynamics
(ELSEVIER SCIENCE BV, 2010)
The magnetic Barkhausen noise (MBN) is a phenomenon sensitive to several kinds of magnetic material microstructure changes, as well as to variations in material plastic deformation and stress. This fact stimulates the ...
