A positional FEM Formulation for geometrical non-linear analysis of shells
(LATIN AMER J SOLIDS STRUCTURES, 2008)
This work presents a fully non-linear finite element formulation for shell analysis comprising linear strain variation along the thickness of the shell and geometrically exact description for curved triangular elements. ...
A FEM procedure based on positions and unconstrained vectors applied to non-linear dynamic of 3D frames
(ELSEVIER SCIENCE BV, 2011)
This study presents an alternative three-dimensional geometric non-linear frame formulation based on generalized unconstrained vector and positions to solve structures and mechanisms subjected to dynamic loading. The ...
Aprendizado de máquina baseado em separabilidade linear em sistema de classificação híbrido-nebuloso aplicado a problemas multiclasse
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2009-06-29)
This master thesis describes an intelligent classifier system applied to multiclass non-linearly separable problems called Slicer. The system adopts a low computacional cost supervised learning strategy (evaluated as ) ...
Estudo dos efeitos da não linearidade geométrica e física sobre o comportamento de uma edificação em concreto armado
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2021-01-15)
The main objective of this work is the study of a building of twelve floors in reinforced concrete, highlighting the influence of the effects of geometric and physical nonlinearity on this structure. In order to consider ...
A piezoelectric beam model with geometric, material and damping nonlinearities for energy harvesting
(IOP Publishing, 2020-09-10)
To predict electrical generation in piezoelectric small-scale beam energy harvesting devices, it is important to have a complete mathematical model that captures the different associated phenomena. In the literature, some ...
Desenvolvimento de programa livre para análise de pórticos tridimensionais considerando-se a não linearidade geométrica, fissuração do concreto e ligações semi-rígidas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECiv, 2007-10-25)
Structural analysis of framed structures using discrete method, wherein, splitting them into elements with simplified considerations, can bring not satisfactory results or end up using very high safety coefficient to the ...
A non-linear multi-objective technique for hybrid peer-to-peer communication
This work proposes a strategy management technique based on hybrid peer-to-peer communication system. The main techniques used in the P2PC are: (i) Multi-objective optimization, (ii) Game theory technique, (iii) Non-linear ...
