Análise dinâmica não-linear de sistemas rígido-flexíveis
… mixed time integration algorithm applied to non-linear problems. The explicit integration is obtained by the Central Difference Method, while the implicit uses the Newmark Operator. Rigid-flexible systems, as soil-fluid-structures problems, are analysed. In the fluid-structure interaction, the …

Análise dinâmica não linear da interação solo-estrutura em plataformas marítimas
This work deals with the dynamic nonlinear analysis of soil-structure interaction in offshore platforms, during its installation and operation. Hence, it was developed a numerical model to allow the representation of the soil fundamental plastic and rheological properties. This model also enhances …

Resposta dinâmica não-linear da interação solo-estrutura no domínio da frequência
… present the system DINAF/NL which allows the nonlinear soil-structure interaction dynamic analysis of bi-dimensional models with applied external loadings using the finite element method. The solution of the dynamic equilibrium equations is done in the frequency domain, through the direct …

Um estudo sobre métodos de integração direta para a análise dinâmica não-linear de estruturas
… aspects of direct integration algorithms for non-linear dynamic analysis by the Finite Element Method. Included here are the Newmark Method, the Central Difference Method and also the treatment of the non-linear terms as pseudo-forces. Some criteria based on energy conservation concepts which are …

Relações de escala em criticalidade no cérebro
… em repouso. Em nossas análises, a classe MF-DP não mostrou ser consistente com os valores médios obtidos experimentalmente, que indicaram novos valores de expoentes em que a relação de escala é satisfeita. Assim, os modelos da classe MF-DP são novamente colocados em xeque para explicar os novos …

Dinâmica e controle de caos de um sistema pendular com memória de forma
This work deals with the dynamics and control of a pendulum system coupled with shape memory alloys (SMAs) springs. To construct the system’s dynamics a polynomial temperature dependent constitutive model for the SMA is employed. The system’s dynamics is characterized displaying a variety of …
