AriffinProblem statement: The use of fracture mechanics techniques in the assessment of performance and reliability of structure is on increase and the prediction of crack propagation in structure play important part. The finite element method is widely used for the evaluation of SIF for various types of crack configurations. Source code program of two-dimensional finite element model had been developed, … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,842 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCreep-Fatigue Crack Growth Interaction in Nickel Base Supper AlloyF. DjavanroodiMost engineering components which operate at elevated temperatures are subjected to non-steady loading during service. This paper describes the current fracture mechanics concepts that are employed to predict cracking of Nickel base supper alloy materials at high temperatures under low and high frequency cyclic loading. A model for predicting creep crack growth in terms of C* and the creep uniaxial … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,892 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTransversely Cracked Beam's Finite Elements with a Hinged EndM. Skrinar, T. PliberšekTwo new beam finite-elements to be used for the transverse displacement analysis of slender beams with transverse cracks are presented where the derivations are based on a simplified computational model. The beam stiffness matrixes are presented in symbolic forms for beams with a single transverse crack and a hinge at one of the nodes. Since in the derivations the corresponding … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,913 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCrack Analysis of Concrete Arch Dams Using Micro-Planes Damage Based Constitutive RelationsM. Labibzadeh, S.A. SadrnejadAmong the various numerical simulating models of plane concrete, the micro-planes models have an excellent position. These models are not as complicated as microscopic models such as discrete particles models and do not have the shortcomings of macroscopic models based on the stress or strain invariants. The object of this study is the application of author's recently developed micro-planes damage … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 6,978 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIn Silico Sequence Analysis, Structure Prediction and Function Annotation of Melanocortin 1 Receptor Gene (MC1R) from the Guppy Poecilia reticulataAbdul Khader Sultan Mohideen, Mehboob Asrar Sheriff, Kareem AltaffThe common guppy, Poecilia reticulata is one of the most popular aquarium fish used as a model organism in toxicology, embryology and genetical studies. Vibrant colors in males are a secondary sexual character which attracts the females for mating. Pigmentation in guppy is found to be linked with melanin synthesis. Melanocortin genes are involved in the synthesis of melanin pigments. … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 17 Nov 2015 · 8,614 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExploratory Study on the Fracture Resistance of Cast GlassTelesilla Bristogianni, Faidra Oikonomopoulou, Fred Veer, Rob NijsseThe emerging interest in the architectural applications of cast glass components reveals a knowledge gap on the mechanical properties of cast glass. Apart from its chemical composition, cast glass is characterized by its manufacturing history and thermal profile, often inheriting a set of defects that define its properties. The role that inhomogeneities in the bulk of voluminous glass components have … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 4 Jun 2021 · 7,356 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Acid Frosting on the Microstructure Characteristics and Mechanical Strength of Eroded Soda-Lime-Silica Glasses by SandstormAkinwumi Gbenga Owoyemi, Grace Olufunke Matthew, Seun Samuel OwoeyeMost glass products such as cars windshields, solar panels protecting glass and windowpanes are exposed to unavoidable sandblasting effects especially in areas prone to sandstorms. This sand impingement results into micro cracks and surface flaws which altered the structure and strength of the exposed glasses thereby lowering their service life. In this regard, attempt was made in this research to … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 25 Apr 2019 · 6,918 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNumerical Study on Coupling Beam Retrofitted Using CFRP and GFRP SheetsSaeideh Hakimi, Rahmat MadandoustOne of the most useful way to resist against earthquake is using coupling beam of steel shear walls. The steel shear wall’s behavior depends on several factors such as stiffness, ductility, strength and so on. But, it has the shear cracks in coupling beam. In this paper, the effect of Carbon Reinforced Fiber Polymer (CFRP) on coupling beams has been … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 6 Aug 2018 · 7,723 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact Behavior of High Strength Concrete Slabs with Pozzolana as Coarse AggregateMahmoud B.A. Alhasanat, Arabi N. Al QadiThis research goal is the adding of pozzolana as rough aggregate in concrete. Pozzolans of Jabl Onyzh have been described as the major supply from Jordan. It is often used in the place of a conservative aggregate in frivolous concrete. A practical examination was carried out on the resistance of Pozzolana Lightweight Concrete (PLWC) with diverse ratios (35 and 50%) … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 14 Jun 2016 · 7,121 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFracture Initiation at the Zirconia/Veneer Interface-A Finite Element SimulationMirsayar M. M., A. T. SamaeiZirconia/veneer bilayered components are extensively used in dental restoration technology to improve resistance of tooth's surface from decay. The direction of the fracture propagation at the interface of zirconia and veneer is investigated in this study. Finite element analysis is performed on a bi-material four point bend specimen in different geometries and the fracture initiation angle is obtained using Maximum … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 8 Jun 2015 · 7,567 accessesView PDFCite
