Case ReportOpen accessAll words, across the recordDemonstration of the Structural Resiliency of Damaged Sentryglas Laminated Heat Strengthened Glass Fins in Full Scale TestingFred Veer, Diana de Krom, Rob NijsseA unique structural design was made for the glass façade of the Co-Creation Center building in Delft. The roof is completely carried by the glass fins. The fins are laterally stabilized by being included in the triple glazed façade. To certify the safety of the design full scale tests on the fins were done at Delft University of Technology. Due … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 11 Feb 2021 · 6,320 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparison 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 PDF Cite

Research ArticleOpen accessAll words, across the recordRating of Spur Gear Strength Using Photoelasticity and the Finite Element MethodKonstandinos G. Raptis, Theodore N. Costopoulos, Georgios A. Papadopoulos, Αndonios D. TsolakisProblem statement: Toothed gears are some of the most used machine elements for motion and power transmission between rotating shafts. This fact induces the need for improved reliability and higher endurance, which require precise and clear knowledge of the gear tooth stress field during meshing. Approach: This study considered the calculation of maximum stress at gear tooth root when the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,879 accessesView PDF Cite

Review ArticleOpen accessAll words, across the recordUnraveling the Mechanisms of Plant Structural Defenses against Insect PestsAroni Preya Biswas, Roksana Al Nafiu Insha, Md. Khairul Mazed et al.Plants employ a variety of physical, chemical, and genetic strategies to defend against herbivore attacks. These biochemical defense mechanisms are complex and dynamic, encompassing both direct and indirect responses. Defense-related chemicals, whether constitutive or induced by herbivore damage, significantly influence herbivore feeding behavior, growth, and survival. Plant defense systems impact herbivore nutrition, development, and survival, highlighting the importance of chemical … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 7 Jan 2025 · 5,793 accessesView PDF Cite

Technical ReportOpen accessAll words, across the recordPolyethylene 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 PDF Cite

Research ArticleOpen accessAll words, across the recordCalibration Coefficients for Residual Stress Measurement in Composite Materials Using Finite Element MethodA. G. Ghasemi, M. AkbarzadehProblem statement: Since the residual stresses can cause a scienificant reduction in strength of the mechanical components, having a semi-destructive measuring method that would predict and model theses stresses would be an advantage. The hole drilling method has been used, by many researches, for measurement of the residual stresses in different materials. In this article, the finite element method is … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 18 Feb 2012 · 9,015 accessesView PDF Cite
