Research ArticleOpen accessEvery word in the titleAdvanced XFEM Simulation of Pull-out and Debonding of Steel Bars and FRP-Reinforcements in Concrete BeamsNicola Orlando, Elena BenvenutiAn innovative three-dimensional model is applied to the pull-out of steel bars and the debonding of FRP plates from concrete specimens. The shearing and opening modes at the interface of debonding is fully captured. The model is based on an innovative variant of the regularized eXtended Finite Element Method (XFEM) developed by the authors. In this method, the displacement discontinuity … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 6 Oct 2016 · 8,295 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,644 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Edge Detection Techniques Applied in the Identification of Centerline Segregation on Steel SlabsLuciene Coelho Lopez Queiroz, André Riyuiti HirakawaThe method Baumann, or Sulphur print as it is also known, is one of the tools used to evaluate the operating conditions of continuous casting machine and quality control of the production of steel slabs. The correct evaluation of centerline segregation severity, analyzed in Sulphur print, is essential to control this process. However, given the classification complexity between the different … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 10 Sep 2015 · 6,825 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,995 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSteel Plates Faults Diagnosis with Data Mining ModelsMahmoud Fakhr, Alaa M. ElsayadProblem statement: Over the last two decades, Fault Diagnosis (FD) has a major importance to enhance the quality of manufacturing and to lessen the cost of product testing. Actually, quick and correct FD system helps to keep away from product quality problems and facilitates precautionary maintenance. FD may be considered as a pattern recognition problem. It has been gaining more … …Journal of Computer Science, Vol. 8, Issue 4 · 31 Jan 2012 · 11,383 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinite Element Analysis of Large Capacity Endplate Steel ConnectionsMohamed Eldemerdash, Taher Abu-Lebdeh, Moayyad Al NasraProblem statement: Extended endplate connection is one of the most widely used beam-to column steel connections because of its fabrication simplicity, good overall performance and cost effectiveness compared with other connection types. The objective of this research is to develop three-dimensional finite element models to study the behavior of large capacity eight-bolt extended un-stiffened wide endplate steel connections, using current-technology … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,915 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermodynamic Characteristics of Camel’s Urine as an Inhibitor for Mild Steel in 1.5 M H2SO4 Acid SolutionEhteram A. Noor, Azza A. Al-Ghamdi, Aisha H. Al-MoubarakiProblem statement: The corrosion inhibition of mild steel in 1.5 M H2SO4 by Camel’s Urine (CU) addition was evaluated at five different temperatures in the range from 30-70°C by weight loss measurements. CU acts as a good inhibitor for the corrosion of mild steel in 1.5 M H2SO4. The value of inhibition efficiency increases with increasing both inhibitor concentration and … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 22 Oct 2011 · 7,373 accessesView PDFCite
