Análise dos procedimentos dos métodos de avaliação de integridade em caldeiras
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2022-06-24)
This work presents a brief theoretical approach of the methods used in the evaluation of boiler integrity and presents professionals' knowledge of the main points of the procedures applied in an inspection and in the ...
DETERMINATION OF THE E/G RATIO OF WOOD LOGS USING TRANSVERSE VIBRATION
(SLOVAK FOREST PRODUCTS RESEARCH INSTBRATISLAVA, 2012)
The Bernoulli's model for vibration of beams is often used to make predictions of bending modulus of elasticity when using dynamic tests. However this model ignores the rotary inertia and shear. Such effects can be added ...

Magnetic Barkhausen Noise in Quenched Carburized Nickel-Steels
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
Two steel sheets, one with 5% Ni and another with 10% Ni, were submitted to carburization and quenching, obtaining a microstructure with martensite and retained austenite. These steels were characterized with magnetic ...
A importancia do fator de equivalencia nos ensaios radiograficos

A new bi-imaging NDT system for simultaneous recovery of attenuation and electronic density maps
(Confédération Française pour les Essais Non Destructifs, 2020)
Computed Tomography is a widely used imaging technique for non-destructive testing and evaluation in industry. Tomographic modalities exploit only primary radiation, which is non-deviated but attenuated radiation going ...
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 ...
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 ...
