Analysis and prediction of welding distortion in complex structures using elastic finite element method
(2012-07)
The Elastic Finite Element Method based on the inherent strain theory is used to predict the welding distortion of ship structures. In addition, a method to predict welding distortion of complex structures by using elastic ...
Numerical analysis of the straightening process of thin plate structures by elastic FEM based on the inherent strain method
(2012-12)
Welding distortion is practically an expected feature in shipbuilding, with a few exceptions; when thick plates are used, for example. Nowadays, the trend is to use thinner plates in order to reduce weight, aiming to reduce ...
On the assumed inherent stability of semi-active control systems
(Elsevier, 2018-03)
Vibration control systems are usually classified into: passive, active and semi-active. Semi-active control systems are based on formerly passive mechanical devices, such as springs and dampers, whose characteristics are ...
Avaliação da degradação de poliamida 11 empregada em cabos umbilicais por viscosidade inerente e reometria em regime oscilatório
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação de Mestrado Profissional em Química - PPGQCâmpus São Carlos, 2020-07-29)
Umbilical cable is one of the main systems for monitoring, powering, and supplying chemicals foroffshore oil and gas wells. Polyamide 11 (PA 11) composes the ducts for the chemical injection andcan suffer ...
Revisão sobre técnicas de controle em estruturas inteligentes
(2005-01-01)
One of the great challenges of structural dynamics is to ally structures lighther and stronger. The great difficulty is that light systems, in general, have a low inherent damping. Besides, they contain resonance frequencies ...

Improvement of damage-assessment results using high-spatial density measurements
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-06)
Model-based damage assessment is based on measuring the distance between experimental and analytical results. In practice, measurements yield only partial mode shapes with respect to the total degrees of freedom present ...
Choosing the Most Suitable Antiseismic Device Technology for High-Rise Buildings, by Considering the Mechanical Response and Environmental Impact
(Springer Science and Business Media Deutschland GmbH, 2023)
In recent years, several earthquakes have drawn the attention of researchers to the effectiveness of antiseismic devices (AD) and structural designs. These elements certainly influence building safety, but they also impact ...
