Research ArticleOpen accessIn the keywordsA Review of the Fatigue Strength of Load Carrying Shear Welded JointsFilippo Berto, Abedin Gagani, Relly Victoria V. Petrescu, Florian Ion T. PetrescuIn the study it is shown an overview of the latest results of two types of joints of the load carrying welded shear. Tests of fatigue have been carried out on the two solutions specific design features proposed and with the aim of improving the resistance of the joints under cycling loading. By hiring the 3D models, was determined Strain … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 2 Jan 2017 · 7,731 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRecent Results on the Brittle Fracture of Terfenol-D Specimens under Magnetic FieldMarco Colussi, Kotaro Mori, Fumio NaritaThe following investigation has the purpose of describing, both experimentally and numerically, the fracture behavior of a giant magnetostrictive alloy commercially known as Terfenol-D. Single-edge precracked specimens have been analyzed via three-point bending tests, measuring fracture loads in the presence and absence of a magnetic field at various loading rates. The Strain Energy Density (SED), averaged in a finite control … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 28 Dec 2016 · 7,772 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractMultiaxial Fatigue Strength to Notched specimens made of 40CrMoV13.9Abedin Gagani, Raffaella Aversa, Relly Victoria V. Petrescu et al.Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocalization of the Dissimilatory Arsenate Reductase in Sulfurospirillum Barnesii Strain SeS-3Eman AfkarProblem statement: Sulfurospirillim barnesii strain SeS-3 is one of the recently known bacterial isolates that can obtain energy to support growth by respiring the toxic oxyanions of arsenic and selenium under anaerobic conditions. Approach: The ultimate goal of this investigation is to localize the active sites for the reduction of arsenate arsenite as well as selenate selenite in S. barnesii … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Presence of Growth and Remodeling in the Bone Adaptation TheorySeyyed Amir Hooshiar Ahmedi, Gholamreza Rouhi, Hamidreza Katouzian, Seyyed Ali Hooshiar AhmediMechanical forces acting on bone during growth affect their final shape and strength. Mechanoregulation of bone growth is maybe recognized in embryogenesis, and also in the adaptation of the adult skeleton to changes in mechanical loading. By combining equations describing bone remodeling and growth with an iterative finite element analysis, a computational model to simulate the simultaneous effects of bone … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,166 accessesView PDFCite
