13. Numerical Study of Vibro-Acoustic Responses of Un-Baffled Multi-Layered Composite Structure under Various End Conditions and Experimental Validation
Abstract This article presents the vibro-acoustic modeling and analysis of un-baffled laminated composite flat panels subjected to harmonic point load under various support conditions. The frequency values of the panel are obtained by using simulation model through the commercial finite element package (ANSYS) via batch input technique. Initially, the rate o

14. Development of a computational instrument using a lagrangian particle method for physics teaching in the areas of fluid dynamics and transport phenomena
Abstract Particle methods are an alternative to the traditional mesh Eulerian methods for solution of fluid dynamics and transport phenomena problems. The Lagrangian Meshless Smoothed Particle Hydrodynamics (SPH) method presents advantages compared to mesh methods as a better visualisation of the spatio-temporal evolution of the flow (and the fluid propertie

15. Oscilación de un disco giratorio visto desde un sistema de referencia en rotación
The ratio relation 1:2 between rotation and wobbling frequencies of a torque free spinning plate or disc as seen from an inertial frame is calculated using a toy model for the disc. From a convenient rotating frame, the body oscillates as a pendulum in a centrifugal field, which simplifies the description of its movement. Thus, the ratio relation is simpler

16. Numerical Study on Steel Shear Walls with Sinusoidal Corrugated Plates
Abstract Over the past decades a growing demand and interest has stimulated many researchers to investigate different aspects of steel plate shear walls (SPSWs). The structural performance of steel shear walls with sinusoidal corrugated plate infills is investigated in this study. Finite element (FE) analysis was adopted using ANSYS software, wherein flat an

17. SIMULATION OF MICROALGAL GROWTH IN A CONTINUOUS PHOTOBIOREACTOR WITH SEDIMENTATION AND PARTIAL BIOMASS RECYCLING
Abstract Microalgae are considered as promising feedstocks for the third generation of biofuels. They are autotrophic organisms with high growth rate and can stock an enormous quantity of lipids (about 20 - 40% of their dried cellular weight). This work was aimed at studying the cultivation of Scenedesmus obliquus in a two-stage system composed of a photobio

18. Comparison of In-Flight Measured and Computed Aeroelastic Damping: Modal Identification Procedures and Modeling Approaches
ABSTRACT The Operational Modal Analysis technique is a methodology very often applied for the identification of dynamic systems when the input signal is unknown. The applied methodology is based on a technique to estimate the Frequency Response Functions and extract the modal parameters using only the structural dynamic response data, without assuming the kn

19. Peripheral Deformation and Buckling of Stainless Steel Hemispherical Shells Compressed by a Flat Plate
Abstract An experimental investigation was performed on stainless steel hemispherical shells under axial compression. Eight kinds of shells with radius-to-thickness ratios that range from 57.1 to 125 were designed and manufactured for this study. The shells were compressed to more than 50% of their radii by a solid flat plate. To avoid contact between the ba

20. A Study of Physical and Numerical Effects of Dissipation on Turbulent Flow Simulations
ABSTRACT: The present work is primarily concerned with studying the effects of artificial dissipation and of certain diffusive terms in the turbulence model formulation on the capability of representing turbulent boundary layer flows. The flows of interest in the present case are assumed to be adequately represented by the compressible Reynolds-averaged Navi

21. Simulação computacional, projeto, construção e análise do desempenho de uma matriz para extrusão em canal angular dedicada ao processamento de chapas / Computational simulation, design, construction and performance analysis of an equal channel angular pressing die for the processing of flat billets
The present work describes the design, construction and testing of an equal channel angular pressing (ECAP) die characterized by rectangular cross section channels. The main parameter of the ECAP dies is the geometry of the channels, given by the angle trough which they meet, and the curvature radii at this point. The material employed in the experiments was

22. Computational modelling of MHD unsteady flow and heat transfer toward a flat plate with Navier slip and Newtonian heating
The combined effects of Navier slip and Newtonian heating on an unsteady hydromagnetic boundary layer stagnation point flow towards a flat plate in the presence of a magnetic field are studied. The self-similar equations are obtained using similarity transformations and solved numerically by a shooting algorithm with a Runge-Kutta Fehlberg integration scheme

24. Aplicabilidad del monitoreo de emisiones del arco eléctrico para el control de calidad en el proceso MAG-S
Ensuring quality in welding is not a trivial task. For this purpose several quality control checks are performed, at the expense, costs and production times are increased. There are several automated welding systems and they are assisted by control systems based on monitoring of welding parameters. However, automated quality monitoring systems are limited an
