Research ArticleOpen accessPhrase in the titleComparison of Maximum Gear-Tooth Operating Bending Stresses Derived from Niemann's Analytical Procedure and the Finite Element MethodAndonios D. Tsolakis, Konstandinos G. RaptisProblem statement: Main purpose of this study was to investigation toothed gear loading problems using the Finite Element Method. Approach: We used Niemann’s equations to compare maximum bending stress which was developed at critical gear-tooth flank point during gear meshing, applied for three distinct spur-gear sizes, each having different teeth number, module and power rating. Results: The results emerging after … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 7,695 accessesView PDFCite
Technical ReportOpen accessPhrase in the titlePolyethylene 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
Case ReportOpen accessIn the keywordsBending Stress and Deflection Analysis of Meshing Spur Gear Tooth during the Single Tooth Contact with Finite Element Method and Determination of the Bending StiffnessAntonios D. Tsolakis, Konstantinos G. Raptis, Maria D. MargaritouPurpose of this study is the study of loading and contact problems encountered at rotating machine elements and especially at tooth gears. Tooth gears are some of the most commonly used mechanical components for rotary motion and power transmission. This fact proves the necessity for improved reliability and enhanced service life, which requires precise and clear knowledge of the stress … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 3 Jun 2017 · 7,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploratory 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 abstractTechnical Stability of Very Slender Rectangular Columns Compressed by Ball-And-Socket Joints without FrictionKrzysztof MurawskiStability of load-bearing members, as known, is a challenging issue and several tools are available for designers. Disregarding the material properties in use, the avoidance of possible stability troubles is a mandatory and challenging step of the overall design process. In this study, a theoretical model is presented for the of loss of stability in elastic states of very slender … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 16 Nov 2020 · 5,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractHoneycomb Sandwich Specimens Made of PLA and Produced Via 3D FDM Printing Process: An Experimental StudySalvatore Brischetto, Roberto TorreIn recent years, the 3D Fused Deposition Modelling (FDM) technology, usually employed for the production of nonstructural objects, has been also used by the present authors for the production of small structural elements where the applied loads are moderate. A typical application could be the production of small Unmanned Aerial Vehicles (UAVs) where stresses are not excessive. In these cases, … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 25 May 2020 · 11,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive Damage Modelling of Transverse Impact Behavior of Adhesively Bonded Composite JointsDimitrios Athinaios, Konstantinos Tserpes, Giannis FlorosA three-dimensional dynamic numerical model was developed, using the commercially available finite element software LS-DYNA to simulate the Low Velocity Impact (LVI) case on bonded joints consisting of woven CFRP adherents. The adhesive failure simulated using the Cohesive Zone Method (CZM), while the failures in the composite material simulated using a progressive damage material model based on Hashin’s failure criteria. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 3 Apr 2020 · 6,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of EVA, PVB and Ionoplast Interlayers on the Structural Behaviour and Fracture Pattern of Laminated GlassLiene Sable, David Kinsella, Marcin KozłowskiArchitectural trends increasingly challenge material producers and engineers to create sustainable, renewable and innovative laminated glass products that combine multiple functions as in, for example, glass railings with solar cells, curved laminated glass, floors with light emitting diodes that serve as multimedia screens. All new tendencies require the development of interlayers for laminated glass, which allows laminating electrical parts, solar … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 5 Jul 2019 · 8,159 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Composite Beams Made of Steel Tubes Filled with Concrete under the Confinement Effect of U-Links and Stud-PlateMoayyad Al-Nasra, Madiha Ammari, Taher Abu-Lebdeh, Abdelqader NajmiConcrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Torsion on Externally Prestressed Segmental Concrete Bridge with Shear KeyM. A. Algorafi, A. A.A. Ali, M. S. Jaafar et al.Externally Prestressed Segmental (EPS) concrete box sections are widely used in the construction of bridge structures today. EPS concept has become an attractive tool for rehabilitation and strengthening of existing bridges which have insufficient strength and/or excessive deflection and cracking. Problem statement: EPS bridges are affected by combined stresses (bending, shear, normal, and torsional) at the joint interface between the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,428 accessesView PDFCite
