Research ArticleOpen accessIn the abstractA Computational Investigation into the Effect of Equal Channel Angular Processing on the Mechanical Properties of Severely Deformed ZK 60 Alloy Validated by ExperimentsOmar Almenaif, Yaqoub Alhumaydani, Mohammed Alnafisah et al.In this study, the response surface method and finite-element analysis were employed to model the ECAP processing for biodegradable magnesium alloy ZK 60 behavior at 250°C. Using Finite-Element (FE) analysis data was extracted and compared to the what was found by experimenting in order to investigate the effects of the ECAP processing parameters on the plastic deformation behavior of the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 9 Jun 2020 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the abstract3D Printing of Porous Scaffolds for Medical ApplicationsAblah Aljohani, Salil DesaiCustom engineered scaffolds that mimic the physiology of native tissue is an emerging need for successful regenerative medicine. One of the key challenges in current manufacturing methods is the lack of controlled porosity throughout the scaffold structure. In this research, our group explores the fabrication of tissue engineering scaffolds using 3D printing technology. The fused deposition modeling method was utilized … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 19 Jun 2018 · 8,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling and Assessment of Effect of Operation Parameters on Gas Turbine Power Plant Performance using First and Second Laws of ThermodynamicsSunday Olayinka Oyedepo, Richard Olayiwola Fagbenle, Samuel Sunday AdefilaIn this study, modelling of gas turbine engine performance is carried out using thermodynamics relations. The model reveals that the influence of operation parameters such as compression ratio, turbine inlet temperature and ambient temperature has significant effect on the performance of gas turbine engine. Energy and exergy analyses were conducted to evaluate the performance of the selected power plant and … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 3 May 2017 · 7,920 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Strength Development in Stabilized Soil with CBR Plus and Silica SandSeyedesmaeil Mousavi, Aliakbar KaramvandThis paper investigates the potential use of a nano polymer stabilizer, namely CBR PLUS for stabilization of soft clay and formulation of an optimal mix design of stabilized soil with CBR PLUS and silica sand. The highway settlements induced by the soft clay are problematic due to serious damages in the form of cracks and deformation. With respect to this, … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 12 Apr 2017 · 7,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of the Nere Pod (Parkia Biglobosa) for the Improvement of Mechanical Properties of SoilsSinko Banakinao, Sonnou Tiem, Kodjo Attipou et al.Buildings made of unbaked clay have some advantage in terms of production cost. However, they have some inconveniences concerning their mechanical performance, particularly their resistance to weather. The objective of this study is to minimize these disadvantages and to maximize the benefits of such buildings to make them more viable. For this purpose, a method based on a traditional practice … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 16 Feb 2017 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractStiffened Panels Damage Tolerance Determination using an Optimization Procedure based on a Linear Delamination Growth ApproachAniello Riccio, Francesco Di Caprio, Francesco Scaramuzzino et al.The damage tolerance of delaminated composite panels under compressive load is usually numerically evaluated by means of computationally expensive non-linear approaches. In this study, an alternative numerical linear approach, able to mimic the delamination propagation initiation, is proposed. With the aim to exploit its benefits, in terms of computational costs reduction, the proposed linear methodology has been used in this … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaThe complex biomechanics and morphology of the femur proximal epiphysis are presented. This specific region in human femur is characterized by a high flexibility compared to that of other primates, since evolved lighter and longer due to the human verticalposition and more balanced loading. The nature and fine morphology of the femur head and its structural behavior have been investigated. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 22 Dec 2016 · 7,855 accessesView PDFCite
