Research ArticleOpen accessIn the abstractComparative Study of Different Underfill Material on Flip Chip Ceramic Ball Grid Array Based on Accelerated Thermal CyclingZ. Kornain, A. Jalar, N. Amin et al.Problem statement: This study mainly to study the effect of several commercial underfill materials to the reliability of HiCTE Flip Chip Ceramic Ball Grid Array (FC-CBGA) package due to Accelerated Thermal Cycling (ATC) effect. Approach: The warpage condition of package, die back stress, interfacial die shear stress, and solder bump fatigue for different commercial underfills were assessed and compared via … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,195 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeismic Response Evaluation of Moment Resistant Frame with Built-Up Column SectionMohammad Ebrahimi, Hesam Sharifian, Mohammad AhangarProblem statement: Moment Resisting Frame (MRF) is widely used as lateral resisting systems when sufficient ductility and deformability are to be met. Response of these structures is strictly dependent upon behavior of their joints, whereas the analysis of steel moment resisting frames generally has been performed without considering the accurate connection behavior. Approach: In this study Finite Element (FE) models … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Joint Flexibility on Overall Behavior of Jacket Type Offshore PlatformsMasoud Mirtaheri, Hossein Ali Zakeri, Pejman Alanjari, Mohammad Amin AssarehProblem Statement: Nonlinear behavior of offshore structure is attracting tremendous amount of attention in recent years. Response of these structures is strictly dependent upon behavior of their joints. Because of the lack of information about this part of a structure, most of the recent analysis and designs do not contain appropriate material in the case of joints. In most cases, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,053 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
Research ArticleOpen accessIn the abstractAnalytical and Numerical Analysis of Free Bulge Tube HydroformingF. Djavanroodi, M. Gheisary, H. Zoghi-shalFree bulge hydroforming simulation was analysied to investigate the biaxial behavior of extruded aluminum tubes. A finite element model was constructed to simulate the hydroforming process and asses the influence of friction between die walls and tube, tube material properties and springback of formed tube. It was found that material hardening coefficient had the most significant influence on formability characteristics … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,863 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeuristic Algorithm in Optimal Discrete Structural DesignsAlongkorn Lamom, Thaksin Thepchatri, Wanchai RivepiboonThis study proposes a Heuristic Algorithm for Material Size Selection (HAMSS). It is developed to handle discrete structural optimization problems. The proposed algorithm (HAMSS), Simulated Annealing Algorithm (SA) and the conventional design algorithm obtained from a structural steel design software are studied with three selected examples. The HAMSS, in fact, is the adaptation from the traditional SA. Although the SA … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,345 accessesView PDFCite
Research ArticleOpen accessIn the abstractMagnetic and Thermal Analysis of Current Transformer in Normal and Abnormal ConditionsM. B.B. Sharifian, M. Farrokhifar, R. Esmaeilzadeh et al.Calculation of Current Transformers (CTs) magnetic and thermal properties are very complex due to the complexity of their construction, different properties of their materials and non-linearity of core B-H curve. Finite Element Methods (FEMs) are very capable and reliable methods for these problems solution, such as Ansys software. In this study Ansys software is applied in analysis of an 800-400/5-5 … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of a Tactile Sensor with Applications in Minimally Invasive SurgeryAshkan Mirbagheri, Siamak Najarian, Javad Dargahi, Farhad Tabatabai GhomsheThis paper describes mathematical modeling of a novel supported tactile sensor. This system has only three or four sensing elements instead of an array configuration. By writing a code, together with using the piezoelectric capabilities of the finite element analysis software, it is possible to extract the stresses developed in the tactile membrane along the edges of the sensing elements, … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,186 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGRAPH OF FINITE SEQUENCE OF FUZZY TOPOGRAPHIC TOPOLOGICAL MAPPING OF ORDER TWOMohamed Sayed, Tahir AhmadFuzzy Topographic Topological Mapping (FTTM) was built to solve the neuromagnetic inverse problem to determine the location of epileptic foci in epilepsy disorder patient. The model which consists of topological and fuzzy structures is composed into three mathematical algorithms. FTTM consists of four topological spaces and connected by three homeomorphisms. FTTM version 1 is also homeomorphic to FTTM version 2. … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 15 Mar 2013 · 7,455 accessesView PDFCite
