Research ArticleOpen accessPhrase 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 · 7,444 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleExperimental Study of Composite Beams Made of Steel Tubes Filled with Concrete under the Confinement Effect of U-Links and Stud-PlateMoayyad Al-Nasra, Madiha Ammari, Taher Abu-Lebdeh, Abdelqader NajmiConcrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,265 accessesView PDF Cite

The solar global radiation and ambient air temperature data used in the system modeling belongs Phitsanulok province from 7 am-5 pm in the summer season. Approach: The system can be divided into two parts, i.e., … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,598 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Cheap Aerial Gas PipelineAlexander A. BolonkinProblem statement: At present time gas pipelines are designed from steel and located on ground surface. That is very expensive and building requests a lot of time. Research and utilization of an old author idea: Design of new cheap aerial pipelines, a large flexible tube deployed at high altitude through neutral seas, for delivery of natural (fuel) gas, water and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,300 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFracture and springback on Double Bulge Tube Hydro-FormingF. Djavanroodi, M. GheisaryThis research aims to establish a basic understanding of Double Bulge Tube Hydro-Form processing of stainless steel deep drawn cups. The method is briefly reviewed by carrying out experimental tests and Finite element analysis. By measuring bulge height in both formed curves by Coordinate measuring machine (CMM) and thickness variation specimen by Ulterasonic thickness measurment device (UTM), it has been … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,894 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopment of Pulsed Laser Deposition System for the Formation of Web-liked Carbon NanotubesNoorhana Yahya, Beh Hoe Guan, Mansor HashimThis work reports on our earnest effort to develop a pulsed laser ablation deposition system for the production of carbon nanotubes (CNTs). The correct condition such as the pressure, ablation time, power of laser will result in different structures and morphology of the tubes. A T-shaped stainless steel chamber was designed. Nd:YAG laser with 532 nm wavelength, 10.54W output power … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,037 accessesView PDF Cite
