Research ArticleOpen accessPhrase in the titleFracture 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 PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractKey-Hole Notches in Isostatic Graphite: A Review of Some Recent DataA. Gagani, Relly Victoria V. Petrescu, Florian Ion T. PetrescuFracture of the breakable isostatic graphite is concerned using the experimental and theoretically, the plates containing nicks holes key subject to varying degrees of mixed task. The main purpose of this work is a double one. In the first place, in order to offer a new set of experimental results on fracture of samples of graphite scored, with different values … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,012 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThree Dimensional Investigation of Mode I Stress Intensity Factor Variations in Crack Front Using Finite Element MethodM. M. MirsayarOverall failure may occur in many engineering structures due to the initiation and growth of cracks. Stress intensity factors are extensively used to investigate crack growth in Linear Elastic Fracture Mechanics (LEFM). In many cracked specimens, the stress singularity varies through the thickness and therefore, investigation of stress intensity factor variation in crack front and determination of its maximum value … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 7,331 accessesView PDF Cite
