1. Two-dimensional beams in rectangular coordinates using the radial point interpolation method
Abstract The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational resources allow the reduction of these simplifications. The most recognized methods of algebraic

2. Verificação da solução das equações de Saint-Venant com base no método difusivo de lax para propagação de vazões em canais naturais
ABSTRACT Hydrodynamic models, based on the Saint-Venant equations, represent the transient flow in water systems, and simulate flow routing over time and space. Several numerical solutions have been applied to these expressions, but often differences are found in results among distinct procedures, considering that all numerical approaches have limitations. N

3. Modelo hidrodinâmico e de transporte bidimensional de grade não estruturada para lagos rasos
Aquatics ecossistems around large towns are always exposed waste domestic and industrial and solid residues. Mathematical models are widely used to understand flow patterns and transport of mass in these ecosystems. In this work a model was developed on unstructured two-dimensional complex dynamic model for shallow lakes. The model was divided in two modules

4. ComparaÃÃo entre duas metodologias de cÃlculo e propagaÃÃo de vazÃes em coletores de redes de drenagem urbana: o mÃtodo racional e as equaÃÃes de Saint-Venant / Comparison enters two methodologies of calculation and propagation of outflows in collectors of nets of urban draining: the rational method and the equations of Saint-Venant
Sistemas de coleta de Ãguas pluviais e drenagem urbana ainda sÃo precÃrios em muitos municÃpios brasileiros. Tais sistemas sÃo projetados para proporcionarem, mesmo em chuvas torrenciais, um fluxo de Ãgua sem inundaÃÃes. Projetistas comumente utilizam o MÃtodo Racional para o cÃlculo da vazÃo e dimensionamento de galerias. Os cÃlculos para tais d

6. Um modelo geometricamente exato de barras com grandes deformações, que considera a distorção e o empenamento geral da seção transversal, e sua discretização pelo método dos elementos finitos. / A fully nonlinear geometrically exact multi-parameter rod model that incorporates general in-plane and out-of-plane cross-sectional changes, and its discretization by Finite Element Method.
The main purpose of this work is to present a fully nonlinear geometrically-exact multi-parameter rod model that incorporates general in-plane cross-sectional changes as well as general out-of-plane cross-sectional warping. The formulation constitutes an extension of the earlier works presented in [1] to [6], [8] and [9], in the sense that the restrictions t

7. Computational model for the study unsteady open-channel flows / Modelo computacional para análise de transiente hidráulico em canais
This work presents a computational model developed in FORTRAN language for the study of unsteady open-channel flows with the use of Saint-Venant one-dimensional equation. The discretization of hydrodynamic equations are presented in a completely implicit method of finite differences and applied in the model for the investigation of two cases, besides the one

8. Modelação matematica do escoamento não permanente nos cursos d agua litoraneos
The unsteady flow in open channels is described by the Saint Venant partial differential equations, wich can be solved by mathematical models provided that the river bed geometric parameters and boundary conditions are known. In engeneering, the application of these models is restricted due to the high cost of the field work required to obtain the geometric
