Research ArticleOpen accessIn the abstractSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,836 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Design Framework for End-of-Life Vehicles Recovery: Optimization of Disassembly Sequence Using Genetic AlgorithmsT. F. Go, D. A. Wahab, M.N. Ab. Rahman, R. RamliProblem statement: It is expected that over the next few years type approval legislation and public awareness will force vehicle manufacturers to identify recovery methods during the design process in order to achieve reuse and recycling targets. Current vehicle design in Malaysia does not sufficiently aid the economic recovery of parts and materials to reach these targets. Approach: This study … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,319 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Review of Constitutive Models for Rubber-Like MaterialsAidy Ali, M. Hosseini, B. B. SahariProblem statement: This study reviewed the needs of different constitutive models for rubber like material undergone large elastic deformation. The constitutive models are widely used in Finite Element Analysis (FEA) packages for rubber components. Most of the starting point for modeling of various kinds of elastomer is a strain energy function. In order to define the hyperelastic material behavior, stress-strain … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 21,709 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Al3Fe5O12 Cubic Structure by Extremely Low Sintering Temperature of Sol Gel TechniqueNoorhana Yahya, Ramadan A.H. Masoud, Hanita Daud et al.Problem statement: Fabrication of nano materials particularly nano inductors at low sintering temperature remains a challenge. This study was carried out as our initial response to obtain a nano-size inductors, which is aluminium iron garnet using low sintering temperature. Approach: The aluminum iron garnet (Al3Fe5O12) nano crystals were prepared by sol-gel technique. The starting solution is a mixture of iron … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,563 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFinite Element Analysis of Frictional Contact Problem During the Process of Metal WorkingNicolae PopThe quasistatic contact problem with dry friction, contributes to the achievement of a numerical model for the simultaneity of different kinds of viscoplastic, incompressible materials forming. Starting from a variational formulation of the problem, which extends the static case, a perturbed Lagrangean, discrete formulation within the framework of finite element method is obtained. On the contact boundary we have used … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,293 accessesView PDF Cite
