Research ArticleOpen accessIn the keywordsFluid-Solid Coupling Analysis on Evolution of In-Situ Stress Field by Water Injection in OilfieldJianjun Liu, Yongxiang Zheng, Bohu Zhang et al.Water injection in oilfield may break initial balance of reservoir and lead to re-distribute of stress and deformation of strata. For further research of the evolution characteristics of in-situ field by water injection, the influence on reservoir by water injection was analyzed and different variables were set to study the effects of depth, injection-withdraw ratio and elastic modulus on strain … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 6 May 2017 · 8,061 accessesView PDFCite
Technical ReportOpen accessIn the keywordsPolyethylene Pipeline Bending Stresses at an InstallationAnatoly Serebrennikov, Daniil Serebrennikov, Zufar HakimovA polyethylene pipeline trenchless installation with special machines is one of methods of gas pipeline constructions between localities. A polyethylene pipeline is exposed to a short term bend and a significant deformation during an installation. The methods and research results of the polyethylene pipeline ability at the short term bending are presented below. The mathematical model has been created. The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 7,938 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Criterion for Determining the Ultimate Pullout Capacity of Plate Anchors in Clay by Numerical AnalysisHaixiao Liu, Fangmei Su, Zhou LiThe Ultimate Pullout Capacity (UPC) is an important index in designing and analyzing plate anchors. However, there are still uncertainties in determining the UPC through the load-displacement curves calculated from numerical analysis. The review on the existing criteria for determining the UPC also demonstrates that there has not been a generally accepted criterion and most existing criteria are not only … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 19 Jan 2015 · 8,413 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Viewpoint for Seismotectonic ZoningReza Derakhshani, Seyed Saeed EslamiProblem statement: Seismotectonic zoning has always been used to get access to intracontinental seismic deformation whereas zoning is not enough reliable in regard with small-scale studies. Approach: This research presents a theoretical model on the basis of plate tectonic theory to introduce a new approach to conduct zoning in terms of seismic deformation. Results: The result of this research not … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the keywordsElapse Time Factor on Induced Vegetative Moisture Uptake in an Unsaturated SoilMuazu Mohammed Abdullahi, Nazri Bn Ali, Kamarudin Bn Haj AhmedProblem statement: Soil consolidation is generally time dependent, therefore soil displacement as a result root water uptake is space and time dependent. The time-dependent nature of abstraction of ground water by vegetation need to be evaluated in order understand the effect of time elapse on matric suction a generation and subsequent ground displacement. Approach: The current approach used the theory … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Approach in Design and Operating Principle of Silicone Tactile SensorBakri Ali, Rozaini Othman, Rasdi Deraman, Muhammad Azmi AyubProblem statement: Research and development in tactile sensor are escalating due to the fact that advanced robot needs to interact with surrounding environments which is very complex, dynamic, uncontrolled and difficult to perceive reliably. Recent research has been focusing in development of new tactile sensor that takes advantage of advances in materials, Micro-Electromechanical Systems (MEMS) and semiconductor technology. To date, … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBioengineering Assessment on Sloppy GroundMu'azu Mohammed Abdullahi, Nazri Bn Ali, Kamarudin Bn Haj AhmedProblem statement: Soft engineering solution of sloppy surface utilizes mechanical and hydrological effects of vegetation. The hydrological effects driven by transpiration, induces an increase in matric suction and consequently tension also increase along with the decrease of moisture. Therefore once the horizontal stress of the soil exceeds the limit of tensile strain of the soil cracks occurs. Approach: The negative … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,242 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnisotropy Influence of Cubic Solid on Dynamic Hertzian Contact Stiffness for a Vibrating Rigid IndenterJiayong TianProblem statement: Resonance-type microscopies have been widely used to evaluate the nanoscaled or microscaled surface elastic properties of materials by the resonance-frequency shifts of an oscillator, which contacts the surface of materials by a spherical tip. Approach: The tip-specimen contact is modeled to be a spring support, whose stiffness is given by the traditional Hertzian contact theory. However, because of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,711 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPrediction of Seismic Active Earth Pressure Using Curved Failure Surface with Localized StrainHemanta HazarikaProblem statement: Correct evaluation of the earth pressure against retaining structure during earthquake is essential for the safe and economic design of geotechnical structures. Progressive deformation in the backfill and the assumed shape of failure wedge affect the calculated values of seismic earth pressures. However, no research until now is available that considers both of these two factors in an … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,547 accessesView PDFCite
