Research ArticleOpen accessIn the abstractPROGRESS OF BIOMATERIALS IN THE FIELD OF ORTHOPAEDICSD. Chandramohan, J. Bharanichandar, P. Karthikeyan et al.The aim of this study is to compare the metallic and natural fiber reinforced polymer composite bone plates used in humerus fractures. A 3D finite element model was developed to analyze the performance of both types of plates. This study proposed on fabrication of natural fiber powdered material (like Sisal (Agave sisalana), Banana (Musa sapientum) and Roselle (Hibiscus sabdariffa)) Reinforced … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 6 Feb 2014 · 7,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractCalibration Coefficients for Residual Stress Measurement in Composite Materials Using Finite Element MethodA. G. Ghasemi, M. AkbarzadehProblem statement: Since the residual stresses can cause a scienificant reduction in strength of the mechanical components, having a semi-destructive measuring method that would predict and model theses stresses would be an advantage. The hole drilling method has been used, by many researches, for measurement of the residual stresses in different materials. In this article, the finite element method is … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 18 Feb 2012 · 9,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganochlorine Pesticide Residues in Fish Samples from Lagos Lagoon, NigeriaDavid Adeyemi, Grace Ukpo, Chimezie Anyakora, JohnPaul UnyimaduThe organochlorine pesticide (OCPs) residues were measured in three species of fish Tilapia zilli (Red belly Tilapia), Ethmalosa fimbriata (Bonga Shad) and Chrysichthys nigrodigitatus (Catfish). These fish species are a significant part of the diet of residents of Lagos Nigeria. The organochlorine pesticides analyzed include DDT(pp'1,1,1-trichloro-2,2-bis-(4-chlorophenyl) ethane), DDD, DDE (pp 1,1-dichloro-2, 2-bis-(4-chlorophenyl) ethylene, HCH (gamma 1,2,3,4,5,6-hexachlorocylohexane, HCB (hexachlorobenzene),Dieldrin (1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a octahydro-1,4,5,8 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Effect of Counterface Materials on Interface Temperature and Friction Coefficient of GFRE Composite Under Dry Sliding ContactN. S.M. El-Tayeb, B. F. Yousif, P. V. BrevernNowadays, there is an increase interest in polymeric composite materials for high-performance in many industrial applications. In other words, the tribo-studies on polymeric materials are growing fast to enhance the polymeric products such as bearings, seals, ring and bushes. The current work presents an attempt to study the correlation between the type of counterface material and frictional heating at the … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDFCite
