Research ArticleOpen accessIn the keywordsPreparation of Magnetorheological Fluids Using Different Carriers and Detailed Study on Their PropertiesVikram G. Kamble, Shreedhar Kolekar, Chetan MadivalarHigh sensitive and intelligence are the main function of the Magneto Rheological Fluids (MRF). In this research work, magneto rheological samples are prepared with two different carrier oils (Honge and Castor) independently. Both the samples are mixed and prepared with same concentration of iron particles. In order to reduce the sedimentation fine lithium grease is added as stabilizer for both … …Current Research in Nanotechnology, Vol. 6, Issue 1 · 4 Sep 2015 · 13,120 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHigh Rate-Dependent Interaction Diagrams for Reinforced Concrete ColumnsTaher Abu-Lebdeh, Sameer Hamoush, Wonchang Choi, Moayyad Al NasraProblem statement: There is a need to better understand the rate dependence behavior of reinforced concrete structures in order to improve their response to impact and blast loads. Analysis and design of reinforced concrete structures subjected to seismic loadings has been recommended in many FEMA guidelines. However, reevaluation of design becomes extremely important in cases where large deformations are expected … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,020 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInterfragmentary ModulusBoonthum WongchaiProblem statement: Young’s modulus and interfragmentary strain (εIF) are the important parameters in bone-plate testing and design. But Young’s modulus is not suitable when we use with εIF in the bone-plate testing. Approach: This research proposed a study on the Interfragmentary Modulus (IM) as the new parameter for the bone-plate testing. Results: The results from the FEM show that the … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 26 Jan 2012 · 7,073 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Lattice Structures for Skin Layer in Camber Morphing WingBashir Alsaidi, Woong Yeol Joe, Muhammad AkbarUnlike conventional fixed wings and their static skin structure considering only expected aerodynamic loadings while filight, design strategies of skin structure for morphing wings require careful consideration of structural loading from shape changes and aerodynamics and their coupled effects in flight. Many morphing wings often overlook skin material and structure for the wing design. In addition to that, many works … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 15 Jul 2019 · 7,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Behavior of Tyre Tread BlockK. Sridharan, R. SivaramakrishnanThe Tyre tread pattern is the arrangement of blocks, grooves and voids, sipes and channels designed into the tread to enhance its grip on the road. Tread is the uppermost part of any tyre which contact into the road and it has its own performance towards mileage, traction, low noise and heat built up properties. It would be meaningful to … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 28 Jul 2012 · 9,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Fully Coupled Approach for Evaluation of Wellbore Stability in Hydrocarbon ReservoirsVera RoccaProblem statement: When a well is drilled in a hydrocarbon reservoir, the original thermodynamic conditions are altered, the natural stresses are redistributed and a stress concentration occurs around the hole. The alteration of the original equilibrium can lead to wellbore damage, sometimes to its complete collapse. Loss of time associated with stability problems is estimated to account for 12-15% of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,559 accessesView PDFCite
Research ArticleOpen accessIn the abstractDurability Assessment of Cylinder Block for Two Stroke Free Piston Linear Engine using Random LoadingM. M. Rahman, A. K. Ariffin, S. Abdullah et al.This research presents the durability assessment of cylinder block for a two-stroke free piston engine using narrow band approach. The life prediction results are worthy for improving the component design at the very early developing stage. This approach is adequate for periodic loading, however, requires very large time records to accurately describe random loading processes. Fatigue damage in conventionally determined … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Stress Analysis of the Arterial Wall Utilizing Physiological Pressure WaveformsM.M. Khani, M. Tafazzoli-Shadpour, S. Delavarpour et al.Arterial diseases, promoted by alterations in arterial wall properties, are among the main causes of mortality. Mechanical stresses of the arterial wall caused by pulsatile luminal pressure define arterial function in normal and pathological conditions. This study aims to determine dynamic stress distribution in the arterial wall subjected to physiological pressure waveforms. Finite element models of a typical artery are … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,163 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCreep predicting model in masonry structure utilizing dynamic neural networkMustafa M. Abed, A. El-Shafie, Siti Aminah Bt. OsmanProblem statement: When the loads are applied to a brickwork structure, visco-elastic behavior upon their stress-strain relationships is exhibited, where the response can be classified into two separate parts: an instantaneous elastic strains and time-dependent creep strains. The creep strain represents the non- instantaneous strain that happens with time when the stress is sustained. Through the previous century, along with … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 7,627 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMesoscopic Damage Based Model for Plane Concrete under Static and Dynamic LoadingsM. Labibzadeh, S. A. SadrnejadThe constitutive equations for the mechanical behavior of concrete capable of seeing damage effects or crack growth procedure under loading/unloading/reloading was developed upon microplane framework. The proposed damage formulation has been built on the basis of five fundamental types of stress/strain combinations, which essentially may occur on any of microplanes. Model verification under different loading/unloading/reloading stress/strain paths has been examined. … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 8,044 accessesView PDFCite
