Today, autonomous robots are used for a variety of applications, ranging from delivering food to operating on patients. A robotic system can be operated with or without human assistance, depending on whether it is manned or unmanned. Additionally, the robot may … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 5 Dec 2022 · 6,745 accessesView PDFCite
Research ArticleOpen accessIn the author namesInvestigation of Sandwich Panel Under High Temperature Loading Using Finite Element AnalysisSajjad Sayyar Roudsari, Armaghan Shalbaftabar, Taher M. Abu-Lebdeh et al.Structural and nonstructural members are always encountered with extreme loading conditions. In case of nonstructural members, the failure happens much sooner due to lack of load capacity. The nonstructural elements are not designed for structural loading conditions. However, they might be impacted to other loading types such as fire. In recent years, the use of 3D panel is one of … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 1 Jul 2020 · 7,678 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnalytical Study of Reinforced Concrete Beams Strengthened by FRP Bars Subjected to Impact Loading ConditionsSajjad Roudsari, Sameer Hamoush, Sayed Soleimani et al.Civil engineers have considered Fiber Reinforced Polymer (FRP) materials to enhance the performance of structural members subjected to static and dynamic loading conditions. However, there are some design limitations due to uncertainty in the behavior of such strengthened members. This fact is particularly important when considering the complex nature of the nonlinear behavior of materials, the impact loading conditions and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 9,929 accessesView PDFCite
Research ArticleOpen accessIn the author namesGas Atomization of Molten Metal: Part II. ApplicationsTaher M. Abu-Lebdeh, Genaro Pérez-de León, Sameer A. Hamoush et al.A numerical model was derived to obtain results for two alloys during the Gas Atomization (GA) method. The model equations and governing equations were implemented through the application of part I data. Aspects such as heat transfer, fluid mechanics, thermodynamics and law of motions were taken into account for the formulation of equations that take gas dynamics, droplet dynamics and … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 19 Apr 2016 · 8,359 accessesView PDFCite
Research ArticleOpen accessIn the author namesGas Atomization of Molten Metal: Part I. Numerical Modeling ConceptionGenaro Pérez-de León, Vincent E. Lamberti, Roland D. Seals et al.This numerical analysis study entails creating and assessing a model that is capable of simulating molten metal droplets and the production of metal powder during the Gas Atomization (GA) method. The essential goal of this research aims to gather more information on simulating the process of creating metal powder. The model structure and perspective was built through the application of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 10 Apr 2016 · 9,047 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Nano Silica on the Compressive Strength of Harden Cement Paste at Different Stages of HydrationJustin Montgomery, Taher M. Abu-Lebdeh, Sameer A. Hamoush, Miguel PicornellThis study investigated the compressive strength of hardened cement paste and the formation of Calcium Silicate Hydrate (C-S-H) with the addition of nano silica (SiO2). Compressive strength testing was performed using MTS and Forney testing machines to determine stress-strain curves and compressive strength of the materials. The hydration process and formation of C-S-H and Calcium Hydroxide (CH) was examined using … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,333 accessesView PDFCite

HamoushThe influence of adding Nano particles of silicon dioxide (SiO2) on cement pastes was studied for both water and vacuum curing methods. Specimens made up of different percentage of Nano Silica were tested at different ages ranging from 3-56 days. The effect of (5-20 nm) Nano-Silica on the strength development of Nano-cement was determined using Material Tests System (MTS). The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 9,084 accessesView PDFCite
Research ArticleOpen accessIn the author namesInvestigating the Role of Fly Ash and Silica Fume in the Cement Hydration ProcessLucas Suarez, Taher M. Abu-Lebdeh, Miguel Picornell, Sameer A. HamoushThis research work investigates the effect of fly ash and silica fume on cement paste hydration. Percentages of each additive were selected to replace the cement by volume to be studied at five different ages using water curing and vacuum curing.
