background: a comprehensive database, comprising geometry and properties of human teeth, is needed for dentistry education and dental research. the aim of this study was to create a three-dimensional model of human teeth to improve the dental e-learning and dental research. methods: in this study, a cross-section picture of the three-dimensional model of the teeth was used. ct-scan images wer...
in this paper, an experimental and numerical investigation into the effect of the hoop welding in metallic pressure vessel is presented. in the experimental manufacturing, hoop welding was used to attach the cylindrical body of the vessel, and the effect of welding into stress and strain distribution is carried out. experimental strains are obtained by using the strain gauges attached to predet...
The paper presents some researches concerning the mechanical properties of composite materials used for prosthetic dental elements. After a short introduction concerning the general strains and loads that usually apply upon prosthetic works, the authors present the virtual model of a molar tooth subjected to the most common actions, using finite element method. Then the results are further show...
This paper presents the prediction of fatigue life and crack propagation in the railway wheel due to the stress field caused by mechanical loads and press fitting process of a railway wheel. A 3-D nonlinear stress analysis model has been applied to estimate stress fields of the railway wheel in press fitting process. Finite element analysis model is presented applying the elastic–plastic fin...
