Research ArticleOpen accessIn the abstractCreep-Fatigue Crack Growth Interaction in Nickel Base Supper AlloyF. DjavanroodiMost engineering components which operate at elevated temperatures are subjected to non-steady loading during service. This paper describes the current fracture mechanics concepts that are employed to predict cracking of Nickel base supper alloy materials at high temperatures under low and high frequency cyclic loading. A model for predicting creep crack growth in terms of C* and the creep uniaxial … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractMagnetic and Thermal Analysis of Current Transformer in Normal and Abnormal ConditionsM. B.B. Sharifian, M. Farrokhifar, R. Esmaeilzadeh et al.Calculation of Current Transformers (CTs) magnetic and thermal properties are very complex due to the complexity of their construction, different properties of their materials and non-linearity of core B-H curve. Finite Element Methods (FEMs) are very capable and reliable methods for these problems solution, such as Ansys software. In this study Ansys software is applied in analysis of an 800-400/5-5 … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Solar Radiation in High Energy Intensive of the World by PV SystemU. Ali RahomaSolar energy can be converted directly into electricity by means of solar cells. Solar cells currently cost around $3.50 per watt for crystalline cells and $2 per watt for thin-film wafers, which are less efficient but can be integrated into building materials. Industry analysts note that between 2000 and 2005, each doubling of cumulative production resulted in a price drop … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,680 accessesView PDFCite

FaiezaDemand for lighter and stiffer products has been increasing in the last few years especially in automobile manufacturing. The closed die forging process of Metal Matrix Material (MMC) is presented as possible solution, since it produces parts with good mechanical properties and lighter weight. A computational modeling of closed die forging process using finite element method and optimization techniques makes … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 8,477 accessesView PDFCite
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 PDFCite
