Research ArticleOpen accessEvery word in the titleStudy of Heat-Treated Steel and Related ApplicationsShu-Ping Chang, Ming-Chen Chen, Jyh-Dong LinNumerous studies conducted after the 921 earthquake in Taiwan in 1999 have reported that because heat-treated steel features relatively unstable mechanics properties, using such steel in welding, bar splicing, or as thread-cutting components in structures may result in lack of resistance to seismic activity. However, nondestructive testing methods that can be used to identify the type of steel delivered to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 30 Oct 2015 · 7,543 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRespiratory Health of Male Steel Workers in the Eastern Coast of Peninsular MalaysiaNurul Ainun Hamzah, Shamsul Bahri Mohd Tamrin, Noor Hassim IsmailA cross sectional study was carried out to determine the prevalence of respiratory symptoms and associated factors with respiratory health among male steel workers. A total of 424 male workers in the steel production plant were recruited using a stratified random sampling. Subjects were interviewed regarding respiratory symptoms using a British Medical Research Council (BMRC) Questionnaire on respiratory symptoms and … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 27 Jun 2015 · 6,934 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFECT OF USING STEEL SLAG AGGREGATE ON MECHANICAL PROPERTIES OF CONCRETESultan A. Tarawneh, Emhaidy S. Gharaibeh, Falah M. SarairehThis study presents an evaluation of the physical and mechanical properties and characteristics of steel slag aggregate concrete in comparison with the typical crushed limestone stone aggregate concrete. Hardened concrete consist of more than 70% aggregate due to the high demand in building construction and the increase of the amount of disposed waste material, suppliers and researchers are exploring the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 8,055 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModification of Carbon Steel by Laser Surface Melting: Part II: Effect of Laser Beam Power on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe surface hardness has an important effect on the wear resistance of different materials. The present study aims to improve the surface hardness of carbon steel through the application of laser surface melting with suitable conditions. The laser beam power and travelling speed are the main factors that affect the properties of the treated zone. In this study, three different … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 30 Jan 2014 · 7,208 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModification of Carbon Steel by Laser Surface Melting: Part I: Effect of Laser Beam Travelling Speed on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study aims to improve the surface hardness of carbon steel by application of laser surface melting of effective conditions. The travelling speed of laser beam during this treatment is one of the important treatment conditions. This study aims to investigate the effect of laser surface melting with different beam speeds on macro and microstructure as well as the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 2 Jan 2014 · 7,400 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSTEEL FIBER CURVATURE IN CONCRETE COMPOSITES: MODULUS PREDICTIONS USING EFFECTIVE STEEL FIBER PROPERTIESAbdellatif SelmiResults in the literature demonstrate that substantial improvements in the mechanical behavior of concrete have been attained through the addition of steel fibers as a reinforcing phase. We have developed a model combining finite element results and micromechanical methods to determine the effective reinforcing modu-lus of hook-ended steel fibers. This effective reinforcing modulus is then used within a multiphase micro-mechanics … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 13 Dec 2013 · 7,051 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Link Dimensions on D Type Eccentric Steel FramesMazen Ali MusmarIn seismic prone regions, buildings are designed to maintain sufficient stiffness during moderate earthquakes and to absorb and dissipate a large amount of the energy released due to severe earthquakes. The usual steel framing systems; the moment frames require larger member sections to satisfy stiffness requirements and have large ductility capacity, the concentrically braced frames satisfy stiffness on the expense … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 12 Feb 2013 · 7,529 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Influence of Foam Density on Specific Energy Absorption of Rectangular Steel TubesNirut Onsalung, Chawalit Thinvongpituk, Kulachate PainthongProblem statement: In general, the automotive structure is targeted to absorb high impact energy with least mass as much as possible. This is in order to limit the fuel consumption. Therefore, various techniques to increase the energy absorption with less mass increment have been studied for years. One of those techniques is by filling foam in the tube. This study … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,440 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeasibility of Using TIG Welding in Dissimilar Metals between Steel/Aluminum AlloyRattana Borrisutthekul, Pusit Mitsomwang, Sirirat Rattanachan, Yoshiharu MutohProblem statement: Currently, in order to suppress intermetallic reaction layer formation during dissimilar metals welding between steel/aluminum alloy, only laser beam welding as self-brazing technique has been applied. However, TIG welding process might be one of welding process candidate for joining dissimilar metals welding between steel/aluminum alloys due to its capability in joining thin section. In the present study, the … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 14,513 accessesView PDFCite
