Análise estática e dinâmica de pórticos espaciais com incerteza no carregamento utilizando o método de elementos finitos
(2015-11-23)
In this thesis, static and dynamic analysis of elastic space frames with regime uncertainty in loading using the finite element method (FEM) are described. A structural approach to the dynamic problem of forced vibrations ...
Um modelo de pesos para a reconstrução de imagens em tomografia por impedância elétrica via mínimos quadrados ponderados aplicável ao monitoramento de fluxo em dutos
(2019-03-26)
This dissertation develops an approach able to improve the quality of least squares image reconstructions from electrical impedance tomography. Thereupon, it is proposed the application of the weighted least squares method, ...
Métodos numéricos não convencionais na abordagem dinâmica em cascas de revolução com simetria axial de forças
(2017-12-21)
This dissertation has as objective presents and checks a series of non-conventional methods for numerical analysis in comparison with the finite element method (FEM) applied commercially. Initially is performed a bibliographic ...
Análise estática de placas e cascas de revolução compostas por laminados sujeitas a carregamentos axissimétricos.
(2018-02-16)
With significant development of the aeronautical, naval and automotive industry from 1960, there was a need to reduce weight, along with the improvement of properties such as mechanical resistance, vibration control, ...
Otimização da orientação de mini-implante para minimizar a possibilidade de falha devido à perda óssea : um procedimento usando algoritmo genético e análise de elementos finitos
(2018-12-20)
From the need for replacement, or repair of human bone structures, the use of implants has become an increasingly common practice in humans. Even with the development and research of methods and materials more technologically ...
