Research ArticleOpen accessIn the abstractTheoretical Analysis and Technical Seismicity Effect Assessment onto the Production Factory due to Traffic in Prešov CityDaniel Papán, Katarína Krkošková, Zuzana PapánováThe technical seismicity effect assessment caused by traffic is the aim of article. The highway structure, as the mine of vibration, includes common layers and also special materials with dumping properties. It is the geomesh reducing the crack creation caused by fatigue, the tension strength increase and excess settlement The stress concentration in the bitumen structure reduces and separates into … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 23 Nov 2017 · 7,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Meshing of Structured Boundary Domains in Numerical AnalysesArnulf Kost, Kokou Tcharie, Ayité Senah Akoda Ajavon et al.The analysis of a practical problem using numerical methods such as Finite Element Method (FEM) or Boundary Element Method (BEM) involves the subdivision of the space occupied by a physical system (named domain) or its boundary into sub-domains or sub-boundaries called elements. This task, known as mesh generation or domain-discretization, is no more trivial if domains of real or industrial … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Oct 2017 · 7,849 accessesView PDFCite
Case ReportOpen accessIn the abstractBending 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 abstractCavern Design Philosophy under High Stress Rock Condition a Case Study in Sri LankaBahram SalehiFor stabilizing of rock cavern stress condition and orientation, rock properties and cavern geometry have determinant effects. Numerical and analytical study and knowledge about self-support arching can assist to designer in appropriate understanding of cavern and ground interaction. The comparative studies by E. Hoek, showed that the mushroom shaped cavern was not an acceptable design because of high value stress … …American Journal of Applied Sciences, Vol. 14, Issue 3 · 21 Mar 2017 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractPiezoelectric Co-Rotational 3-Node Shell ElementGil Rama, Dragan Marinkovic, Manfred ZehnGeometrically nonlinear FE-analysis of active piezoelectric thin-walled shell structures, based on a Co-Rotational (CR) formulation and the Cell-Smoothed Discrete-Shear-Gap 3-node shell element (CS-DSG3) is presented in this study. The electric potential across the thickness of piezolayers is approximated by a linear function. The basic assumption of the applied Co-Rotational (CR) FEM formulation is that translations and rotations are finite, whereas … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 15 Oct 2016 · 7,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobustness of XFEM Method for the Simulation of Cracks Propagation in Fracture Mechanics ProblemsAniello Riccio, Umberto Caruso, Antonio Raimondo, Andrea SellittoIn the present paper a numerical sensitivity analysis is presented with the aim to assess the effectiveness of the X-FEM method for fracture mechanics applications. Different test cases have been adopted for the numerical analyses to point out the X-FEM method behavior in 2-D and 3-D elastic and elasto-plastic conditions. Comparisons with a standard ductile damage model have been carried … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 15 Aug 2016 · 8,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of a Machine Tool Spindle Critical Frequency through Modal and Imbalance Response AnalysisKhairul Jauhari, Achmad Widodo, Ismoyo HaryantoThe most important part for machine tool system is spindle system.
