1. Nonlinear static analysis of a pile-supported wharf
Resumo O objetivo deste artigo é desenvolver uma análise estática não-linear através de um estudo de caso de um cais sobre estacas situado em uma nova área portuária para petroleiras. A atividade sísmica da área é muito intensa com uma aceleração máxima do solo de 0.55 g. Por esta razão, é muito importante analisar o comportamento estrutural n

2. Simplified expressions for dynamic behavior of cylindrical shells uncoupled and coupled with liquids
Abstract The dynamic behavior of cylindrical shells is essential in many practical applications. These include in-vacuum and coupled vibrations of structures with contained fluids. Closed-form solutions are extremely complex since they involve many terms and algebraic operations that require numerical solvers. In this work, a simplified closed-form solution

4. Evaluación reológica de fluidos de perforación base agua con nanosílice
ABSTRACT Generally, drilling fluids may be defined as fluids with a composition that can assist the generation and removal of cuttings from the borehole to the surface. They are classified according to their base as water based mud (WBM), oil based mud (OBM) or gas. Polymers, densifiers, brines, surfactants, among others are the primary components of drillin

5. Experimental and Numerical Investigation of the Dynamic Behavior of Clamped Thin Panel Subjected to Underwater Impulsive Loading
Abstract The dynamic response and failure mechanism of clamped thin aluminum alloy plates subjected to underwater impulsive loading are investigated by laboratory experiments and finite element (FE) simulations. The effects of plate thickness, impulsive loading and fluid-structure interaction on failure modes in clamped thin aluminum plates are comprehensive

6. Experiment and Calculation Method of the Dynamic Response of Deep Water Bridge in Earthquake
Abstract For deep-water long span bridges under earthquakes, the interaction between water and structure will inevitably induce the hydrodynamic force on the structures. Based on the Morison potential fluid theory, a simplified calculation method of hydrodynamic force was proposed. Taken the 3rd Nanjing Yangtze River Bridge in China as the prototype, the sha

7. Pressure-Based and Potential-Based Differential Quadrature Procedures for Free Vibration of Circular Plates in Contact with Fluid
Abstract The differential quadrature method (DQM) has been so far applied to a wide variety of fluid and/or structural problems. The results of many researchers reveal that the DQM is computationally efficient and is applicable to a large class of boundary value problems. However, there is little information about its applications to fluid-structure interact

8. A Review on Aerodynamics of Non-Flapping Bird Wings
ABSTRACT Birds are known for their agility, manoeuvrability, and flexibility during flight. These features allow their ability to fly under a large range of flight conditions. Bio flyers and bio aerodynamic/fluid surfaces have inspired many to perform experiments and simulations as well as to relate their results to engineering applications. Wings specifical

9. Dynamic responses and damages of water-filled cylindrical shell subjected to explosion impact laterally
An account is given of some principal observations made from a series of experiments in which metal cylindrical shells were subjected to lateral explosion impact by different TNT charge mass and stand-off distance. These cylindrical shells were filled with water in order to identify the main effects produced by the fluid-structure interaction. In comparison,

10. Seismic response of aboveground steel storage tanks: comparative study of analyses by six and three correlated earthquake components
Ground motions at a point on the ground surface can be decomposed to six components, namely three translational components and three rotational components; translational components include two components in the horizontal plane, and one in the vertical direction. Rotation about horizontal axes leads to rising of rocking, while the rotational component about

11. Estudo de propriedades petrofísicas de rochas sedimentares por Ressonância Magnética Nuclear / Petrophysical properties study of sedimentary rocks by Nuclear Magnetic Resonance
The Nuclear Magnetic Resonance (NMR) technique is one of the most versatile techniques for scientific research, specially for the study of dynamics, structure and conformational of materials. In particular, its application in oil science is one of its first routine applications. Methodologies developed specifically to match this scientific community proved t

12. Escoamento de fluidos complexos e transporte de partÃculas em geometrias irregulares. / Complex fluid flows and particle transport in irregular geometries.
In this work many types of incompressible laminar Newtonian and Non-Newtonian flows are studied. The interplay of these flows with complex geometries was investigated using computational modeling and numerical solution of the conservation of momentum and mass continuity equations. As a first step, the computational modeling of a network of pores was adopted
