1. Proposal of a method for service life prediction of a concrete structure: a case study
Abstract This article presents a method for service life prediction of concrete structures. The proposed method aims to estimate the performance of a concrete structure through its permeability to carbon dioxide penetration, in order to verify its accordance to Brazilian standards. This case study is based on an inspection made in an educational building in

3. Photonic Imaging with Optical Coherence Tomography for Quality Monitoring in the Poultry Industry: a Preliminary Study
ABSTRACTA photonic imaging method that gives the possibility to measure egg quality was applied. Since the method is non-contact and non-destructive we believe that this photonic imaging method may be successfully integrated in the automated inspection systems in the poultry industry. The method involves scanning an invisible infrared light beam over the egg

4. Caracterización de semielaborados de aleaciones de titanio procesadas por extrusión y laminación perforación (proceso Mannesmann)
ABSTRACTFor the manufacture of seamless pipes and tubes are used, as raw materials, hollow bars from hot deformation processes like extrusion and rotary tube piercing (Mannesmann process). Starting from these semi-elaborated products and by means of successive cross sections reductions through tube drawing or tube rolling (cold pilgering) the requested final

5. Optimization and non-destructive test analysis of SS316L weldments using GTAW
This work aims at optimization and analysis of SS316L weldments using TIG Welding, SS316L is selected over other grades because of its lower carbon content and its weldability properties. The welding parameters are being assessed by means of Taguchi's L9 orthogonal array with varying gas flow, current and bevel angle with the predictions achieved the sample

6. Simulação da propagação de ondas ultrassônicas longitudinais em materiais estruturais aeroespaciais / Simulating the propagation of longitudinal ultrasonic waves in aerospace structural materials
The use of composite materials in the aerospace industry is increasing due to its low ratio between density and mechanical strength. To perform non-destructive testing using ultrasound, it is necessary to know the sound velocity in these materials. It is not always possible to manufacture physical prototypes during the development of a project because of tim

7. Architecture of a remote impedance-based structural health monitoring system for aircraft applications
The essence of structural health monitoring (SHM) is to develop systems based on nondestructive inspection (NDI) technologies for continuous monitoring, inspection and detection of structural damages. A new architecture of a remote SHM system based on Electromechanical Impedance (EMI) measures is described in the present contribution. The proposed environmen

8. Aplicação de métodos não destrutivos para qualificação de combustíveis tipo dispersão de U308-Al e U3Si2-Al no reator IEA-R1 / Application of non-destructive methods for qualification of the U3O8-Al and U3Si2-Al dispersion fuels in the IEA-R1 Reactor
IPEN/CNEN-SP manufactures fuels to be used in its nuclear research reactor the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil doesnt have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP

9. Utilização de métodos não destrutivos e semi destrutivos na avaliação de pontes de concreto. / Use of non-destructive methods and semi-destructive evaluation of concrete bridges.
As estruturas de concreto, especialmente as pontes de concreto, estão sujeitas a um conjunto de ações que leva ao seu envelhecimento devido aos processos de deterioração, muitas vezes deixando de responder às exigências para as quais foram projetadas. Tal situação, em muitos casos, é agravada pela falta de conhecimento dos processos e mecanismos de

12. Ultrasonic inspection of AA6013 laser welded joints
Interest in laser beam welding for aerospace applications is continuously growing, mainly for aluminum alloys. The joints quality is usually assessed by non-destructive inspection (NDI). In this work, bead on plate laser welds on 1.6 mm thick AA6013 alloy sheets, using a 2 kW Yb-fiber laser were obtained and inspected by pulse/echo ultrasonic phased-array te
