Research ArticleOpen accessIn the abstractEffect of Torsion on Externally Prestressed Segmental Concrete Bridge with Shear KeyM. A. Algorafi, A. A.A. Ali, M. S. Jaafar et al.Externally Prestressed Segmental (EPS) concrete box sections are widely used in the construction of bridge structures today. EPS concept has become an attractive tool for rehabilitation and strengthening of existing bridges which have insufficient strength and/or excessive deflection and cracking. Problem statement: EPS bridges are affected by combined stresses (bending, shear, normal, and torsional) at the joint interface between the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,428 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of Blood Turbulent Flow in Carotid Artery Including the Effects of Mural Thrombosis Using Finite Element ModelingM. Arab-Ghanbari, M. M. Khani, A. Arefmanesh, F. Tabatabai-GhomsheArterial thrombosis is an extremely significant health problem. As a result of numerous factors involved in such problem, describing the role of hemodynamics in thrombogenesis has been asserted to be one of the most demanding and complicated challenges in biomechanics. An axisymmetric model considering fluid-structure interactions (FSI) was introduced and numerically solved for an artery with a thrombosis to perform … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,408 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermination of Rheological Properties of Bio Mastic AsphaltR. Muniandy, H. Jafariahangari, R. Yunus, S. HassimDue to the high oil prices the price of asphalt binder has increased tremendously. This scenario has warranted demand for higher viscosity cheaper asphalt for pavement construction. A study was conducted to take advantage of the Empty Fruit Bunch (EFB) of Date and Oil Palm trees (which are considered as waste) to produce cellulose fiber to be used as additives … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 8,067 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFlow Characteristics in Elastic Arteries Using a Fluid-Structure Interaction ModelH. Niroomand Oscuii, M. Tafazzoli Shadpour, Farzan GhalichiIn this study the interaction of blood flow with arterial wall has been investigated using FSI (Fluid-Structure Interaction) modeling. Computer simulation of pulsatile blood flow was carried out on the basis of the time dependent axisymmetric Navier-Stokes equations for an incompressible Newtonian fluid flow. An elastic incompressible material with large deformation was considered for the arterial wall and momentum and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,429 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPiezoelectric Co-Rotational 3-Node Shell ElementGil Rama, Dragan Marinkovic, Manfred ZehnGeometrically nonlinear FE-analysis of active piezoelectric thin-walled shell structures, based on a Co-Rotational (CR) formulation and the Cell-Smoothed Discrete-Shear-Gap 3-node shell element (CS-DSG3) is presented in this study. The electric potential across the thickness of piezolayers is approximated by a linear function. The basic assumption of the applied Co-Rotational (CR) FEM formulation is that translations and rotations are finite, whereas … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 15 Oct 2016 · 7,810 accessesView PDF Cite
