Research ArticleOpen accessPhrase in the titleIdentification of Shear Band using Elastic Shear Wave PropagationT. Nachiengtai, W. Chim-Oye, S. Teachavorasinskun, W. Sa-NgiamviboolLocalization in soil under high stress level is usually investigated using some indirect measures, e.g., X-ray diffraction method. In the present study, the propagation velocity of shear wave was used to detect localization in sandy soil. Firstly, the general expression to exhibit the stress and density dependencies characteristics under consolidation and triaxial testing conditions of the tested soil was proposed. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 6,794 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Rotation Effect on Shear Horizontal Surface Wave in a Piezoelectric Semi-Space Covered by a Semiconductor FilmFatimah AlshaikhIn this study, a mathematical model of the rotation effect on Shear Horizontally wave (SH-wave) propagation in a piezoelectric semi-space covered by a semiconductor film is investigated. The semiconducting layer is rotating with a constant angular velocity and the interface between the piezoelectric substrate and the semiconductor layer is imperfectly bonded. Furthermore, the surfaces of the bilayer system assumed free … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 29 Apr 2017 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Contribution of the CDP Gathers and Pre-Stack Seismic Inversion in the Prospect Evaluation: A Case Study of El Mansoura Field, Nile Delta, EgyptMohamed Hussein, Ahmed Abu El-Ata, Mohamed El-BehiryThis case study showing the usefulness of the Common Depth Point (CDP’s) analysis to assess the amplitude response which is similar at two cases (gas-bearing and dry sands) after stack, using the Amplitude Versus Offset (AVO) analysis and the pre-stack inversion to understand the reservoir configuration and its relationship to the different amplitude response. The results led to a high … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 24 Jul 2019 · 7,794 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSimplified Analysis of the Lining Behavior During Earthquakes in Deep Rock TunnelsPierpaolo OresteThe sizing of the lining of a tunnel requires to consider not only the static loads transmitted from the surrounding rock, but also the effects of earthquakes on the stresses and strains of the lining. The detailed evaluation of the interaction earthquake-lining using numerical methods typically requires very long calculation time and can be limited to the verification of the … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 4 May 2015 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel River Meander Migration and Cutoff Model: A New PerspectiveYoussef Ismail HafezAccurate prediction of river meander migration is crucial for effective river management and operation, particularly in light of climate changes and human-induced interventions. Existing models often rely on single-equation approaches, such as bank erosion rate versus excess bank velocity or excess bank shear stress, which limit their ability to comprehensively capture the complex dynamics of meander evolution. This study presents … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 21 Mar 2025 · 7,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Behavior of Steel Composite Shear Wall with Corrugated Plate under Lateral LoadSeyedeh Asma MirfazliJirdehiThe steel shear wall system has been considered as a structural system over the past few decades. This issue deals with wind and earthquake lateral forces due to its hardness, loading capacity and plasticity. This type of the system, with the use of external hardness resulting from the geometric shape of the waves, has better buckling strength than a hardened … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 14 Jul 2018 · 7,900 accessesView PDFCite
Research ArticleOpen accessIn the abstractShort Period Spectral Acceleration Zonation of Tehran a Comparison between Slip and Activity Rates Data’sHadi Jarahi, Noushin Naraghiaraghi, Malihe NadalianThis study presents seismic hazard analysis and provides spectral iso acceleration maps based on slip rate (SR) and also activity rate (AR) of the faults. Nowadays modern seismic design of structures is complicated so special attention to the nature of the seismicity in active seismic zones like Tehran is required. Many studies, based on seismic hazard analysis have been done … …Current Research in Geoscience, Vol. 6, Issue 1 · 18 Feb 2016 · 8,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Sine and Cosine Components in Love Waves and Rayleigh Waves for Energy Hauling during EarthquakeZainal Abdul Aziz, Dennis Ling Chuan ChingProblem statement: Love waves or shear waves are referred to dispersive SH waves. The diffusive parameters are found to produce complex amplitude and diffusive waves for energy hauling. Approach: Analytical solutions are found for analysis and discussions. Results: When the standing waves are compared with the Love waves, similar cosine component is found in both waves. Energy hauling between waves … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Liquefaction Return Period for Bangalore Based on Standard Penetration Test Data: Performance Based ApproachK. S. Vipin, T. G. SitharamProblem statement: The conventional liquefaction evaluation is based on a deterministic approach. However in this method the uncertainty in the earthquake loading is not properly taken into account. However recent research in this field indicates that this uncertainty in the earthquake loading has to be considered in the liquefaction potential evaluation. Moreover the evaluation of liquefaction return period is not … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,741 accessesView PDFCite
