Research ArticleOpen accessPhrase in the titleAn Assessment of Compressive Size Effect of Plane Concrete Using Combination of Micro-Plane Damage Based Model and 3D Finite Elements ApproachM. Labibzadeh, S. A. Sadrnejad, M. NaisipourIn recent years, the material behavior dependence of laboratory concrete specimens built with the same concrete mixture under the same load conditions to their geometrical sizes is well established. This phenomenon which is observed not only in concrete but also in most quasi-brittle materials such as rock, ceramic or composite materials is now called as size effect. Many of the … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,005 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Study of the Effect of Infilled Brick Walls on Behavior of Eccentrically Braced Frames Using Explicit Finite Elements MethodAmir Saedi Daryan, Masood Ziaei, Ali Golafshar et al.Problem statement: Eccentrically Braced Frames (EBFs) are usually infilled by masonry walls, but in common design, the stiffness and lateral resistance of these walls is ignored. Considering the results of carried out tests and studies, it seems that infilled masonry walls have a significant influence on the stiffness and the strength of EBFs. Since experimental test of total frame with … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,191 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTransversely Cracked Beam's Finite Elements with a Hinged EndM. Skrinar, T. PliberšekTwo new beam finite-elements to be used for the transverse displacement analysis of slender beams with transverse cracks are presented where the derivations are based on a simplified computational model. The beam stiffness matrixes are presented in symbolic forms for beams with a single transverse crack and a hinge at one of the nodes. Since in the derivations the corresponding … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMathematical Formulation and Numerical Implementation of a Finite Element with Anisotropic GeometryDavide TuminoA plane quadrangular element with geometric anisotropy has been developed to perform 2D Finite Elements Analyses in cases where high stress concentrations, varying with very different laws along two orthogonal directions, are present. The element has been implemented into a finite element code. To validate the element behavior, analyses in the adhesive of a single lap joint and in a … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 13 Mar 2020 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNonlinear Analysis of RC Box Culverts Resting on a Linear Elastic SoilDaniele Baraldi, Fabio Minghini, Enrico Tezzon, Nerio TulliniIn the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 8 Feb 2018 · 12,632 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Rutting Depth in Flexible Pavements by Using Finite Element Analysis and Local Empirical ModelAlaa H. Abed, Adel A. Al-AzzawiThe objective of this research is to predict rut depth in local flexible pavements. Predication model in pavement performance is the process that used to estimate the parameter values which related to pavement structure, environmental condition and traffic loading. The different local empirical models have been used to calculate permanent deformation which include environmental and traffic conditions. Finite element analysis … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,741 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFinite Element Analysis of Large Capacity Endplate Steel ConnectionsMohamed Eldemerdash, Taher Abu-Lebdeh, Moayyad Al NasraProblem statement: Extended endplate connection is one of the most widely used beam-to column steel connections because of its fabrication simplicity, good overall performance and cost effectiveness compared with other connection types. The objective of this research is to develop three-dimensional finite element models to study the behavior of large capacity eight-bolt extended un-stiffened wide endplate steel connections, using current-technology … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCrack Analysis of Concrete Arch Dams Using Micro-Planes Damage Based Constitutive RelationsM. Labibzadeh, S.A. SadrnejadAmong the various numerical simulating models of plane concrete, the micro-planes models have an excellent position. These models are not as complicated as microscopic models such as discrete particles models and do not have the shortcomings of macroscopic models based on the stress or strain invariants. The object of this study is the application of author's recently developed micro-planes damage … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 6,978 accessesView PDFCite

Research ArticleOpen accessIn the abstractInfluence of Orthodontic Movement by Bracketless Orthodontic Treatment on Stress Distribution: 3D Finite Element AnalysisGuaracy Lyra da Fonseca Junior, Ney Tavares Lima Neto, Evelyne Pedroza de Andrade et al.The Bracketless Orthodontic Treatment (BOT) is an alternative technique with the concept of installing an orthodontic appliance composed only of wires and composite resin with the aid of 3D technology. However, the biomechanical behavior of this therapeutic modality has yet to be elucidated in the scientific literature. Thus, the objective of this study was to evaluate the stress distribution in … …Current Research in Dentistry, Vol. 12, Issue 1 · 4 Jul 2021 · 11,613 accessesView PDFCite
