2. Simulação do Processo de Soldagem Elétrica por Centelhamento de um Aço para Trilhos Ferroviários. Parte 1: Análise de Tensões Residuais Via Elementos Finitos
Resumo Trilhos longos, soldados pelo processo Flash Butt Welding (FBW), são a realidade das ferrovias brasileiras de média e alta carga por eixo. Embora apresentem características desejáveis do ponto de vista do comportamento dinâmico da via, as soldas são regiões de descontinuidade estrutural e mecânica onde se originam tensões residuais, e que est

3. Historical errors in the initial conception of the euro and its subsequent development
RESUMO Em 1992, o Conselho Europeu lançou a União Econômica e Monetária (UEM). O início do euro seguiu-se em 1999. Desde então, a UEM sofreu avarias graves, sobretudo durante a recente crise da Zona Euro em 2010. Para compreender o atual enigma da Zona Euro (EZ), é necessário analisar as circunstâncias em que a UEM foi designada. Ao longo do seu des

7. Fretting corrosion tests on orthopedic plates and screws made of ASTM F138 stainless steel
Introduction Although there has been significant progress in the design of implants for osteosynthesis, the occurrence of failures in these medical devices are still frequent. These implants are prone to suffer from fretting corrosion due to micromotion that takes place between the screw heads and plate holes. Consequently, fretting corrosion has been the s

8. Study of structural capacity and serviceability affecting the obstruction of residential door
The last Chilean earthquake, occurred on February 27, 2010, allowed establishing important patterns of structural failures in reinforced concrete residential buildings; however, limited progress has been made in the study of basic standards of serviceability, such as obstruction of doors. Thus, this study focused on measuring the influence of design specific

9. Polyurethane structural adhesives applied in automotive composite joints
In recent years structural adhesives technology has demonstrated great potential for application due to its capacity to transform complex structures into solid unitary and monolithic assemblies using different materials. Thus, seams or joints integrate these structures providing, besides a reduction in weight, a considerable increase in the mechanical resist

10. MONITORING FLEXIBLE RISERS WITH OPTICAL FIBER SENSORS / MONITORAMENTO DE RISERS FLEXÍVEIS COM SENSORES A FIBRA ÓPTICA
The interest in structural health monitoring of flexible risers has grown significantly in recent years. For ducts that are already reaching their design life, monitoring systems can provide early warnings of potential failures and also assist the operator in scheduling downtime. Different techniques are being tested by operators of flexible pipes such as au
