Research ArticleOpen accessIn the keywordsA Simplified Two-Dimentional Unit Cell Model for Analyzing the Transverse Shear Stiffness of Three-Dimentional Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a complex three-dimensional model affects the speed of calculation time. A simplified two-dimensional model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents a study on the analysis of the transverse shear stiffness of three-dimensional truss-like core sandwich beam using a simplified two-dimensional unit … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,176 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Simplified Analytical Modeling of the Hole Erosion TestMohammed Bezzazi, Abdellatif Khamlichi, Miguel Prron Vera et al.Problem statement: Internal erosion occurs in soils containing fine particles under the action of high pressure gradients that could result from water discharge. This phenomenon can yield in its final stage to the formation of piping which constitutes a real threat for hydraulics infrastructures as it can precipitate their entire rupture in very short time. In order to mitigate this … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,025 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNumerical Study of Airflow around Vehicle A-pillar Region and Windnoise Generation PredictionM. H. Shojaefard, K. Goudarzi, H. FotouhiFlow separation and reattachment around the vehicle A-pillar region dictates strong pressure fluctuations on the side window surfaces and can also lead to generate aerodynamic noise. The objective of this work is to investigate qualitative flow visualization of airflow behaviour around vehicle A-pillar and its potential to generate windnoise in this region. By means of Computational Fluid Dynamic (CFD) under … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,335 accessesView PDF Cite
