Finite Element Analysis Using 2D Plane Stress Elements for Thick Beam
Abstract: Displacements and stresses are calculated for the cantilever model using two-dimensional plane stress finite element analysis (FEA) procedure. The cantilever models are developed using nine-noded Lagrangian (LAG-9) elements with application of boundary and loading conditions. The discretization, formulation of an element, constitution of element, application of load and various boundary conditions by FEA. Analyzing finite element system and computation of its results, namely stresses and displacements are programmed using MATLAB®. …

Modelling Initial Design of Steel Portal Frame using ANN
Abstract: Structural Engineering involves the understanding and modeling of natural phenomenon, material behavior and laws of mechanics, intuition, past experience or expertise and knowledge of analysis techniques. Especially in structural design, the difficulty in problem definition and the large number of constraints makes it difficult to program a machine for computerization of the total design process. The analysis of structure is performed based on the initial design and redesign of the …

Damage Potential of Extreme Wind Events– Downburst and Tornado
Abstract: Thunderstorms have always impressed humans and cumulonimbus cloud is one of the most visually striking and photogenic natural phenomena. Unfortunately, the thunderstorms are associated with hazardous weather. Severe thunderstorms are responsible for large amount of wind induced damage around the globe. Unlike large and continental cyclones, severe local storms intensify very rapidly and dissipate after causing damage. Lightning causes many fires around the world each year and leads to severe …

Comparative Study of Turbulence Models for the Simulation of Three-Dimensional Transonic Flow around Airfoils
Abstract: The analysis of three dimensional transonic flows was carried out on the well-known ONERA M6 airfoil. In this paper three turbulence models i.e. Spalart-Allmaras, k-ω shear stress transport (SST) and k-ε Realizable were compared for transonic flows and validated through comparison with the experimental measurements and CFD results obtained from NASA ONERA M6 study for the selected wing. The discretization of the computational domain was done using an unstructured mesh, …

Investigation of a Possibly EF2 Tornado that had Occurred in the City of Shillong (India) on the 5th of April 2016
Abstract: From the wide range of available literature it can be seen that HIW (High Intensity Winds) have a very significant effect on not only earth fixed structures but also on aviation structures aero planes or helicopters to be specific. Of the available HIW two important events have received wide attention namely Tornadoes and Downbursts. According the Glossary of Meteorology, a tornado is "A violently rotating column of air, pendant from …

High Lift to Drag Ratio for 3D Printed Airfoil for UAV’s: An Experimental and Computational Study
Abstract: Airfoils play a pivotal role in the performance of aerodynamically designed bodies. Lift to Drag ratio is one of the primary parameters based on which the efficiency of airfoil’s are characterized. UAV’s are gaining acceptance around the world for the wide range of operations that can be remotely controlled. The primary objective of current work is to narrow in on an airfoil which is capable of producing high lift to …

A Study on Aircraft Anti-Icing Systems
Abstract: Aircraft anti-icing system is one of the key components without which aircraft icing related problems cannot be solved. Considering the long history of aircraft building technologies the involvement of anti-icing system has a remarkable influence over it. Basically there exist two types of aircraft anti-icing systems namely, the first one is electro-thermal anti-icing system the second one is bleed air anti-icing system. For propellers electro-thermal anti-icing system is used and …
