Software-defined laser ultrasonics: Non-destructive testing
(Society of Photo-Optical Instrumentation Engineers, 2019-09)
In this work we propose and implement the use of software defined optical interferometry for the development of laser ultrasound non-destructive testing. The interferometer is conceived as an optoelectronic system that can ...
Dimensionamento de descontinuidades em peças metálicas por aproximação de Born da amplitude de espalhamento
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2018-12-14)
This work presents a sizing method for inner metal bodies flaws, through ultrasonic A-scan signals generated by a phased array probe. The sizing technique makes use of the scattering matrix, from which the flaw pulse-echo ...
Framework para auxílio no desenvolvimento de algoritmos de reconstrução de imagens em ensaios não destrutivos por ultrassom
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2019-06-28)
Non-destructive tests by ultrasound are actively used in industry, especially in the metallurgical, naval and oil and gas areas, as they detect defects and discontinuities characteristic of the production process itself. ...
Ultrasonic techniques for the detection of discontinuities in aluminum foams
(American Institute of Physics, 2017-02)
Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure, that is the metals or metal alloys foamed include gas voids in the material. Their particular lightweight ...
Medição do perfil de velocidade por técnica ultrassônica utilizando o método da autocorrelação estendida e equipamento para ensaios não destrutivos
