Research ArticleOpen accessIn the abstractDesign and Simulation of Microelectromechanical System Capacitive Shunt SwitchesHaslina Jaafar, Othman Sidek, Azman Miskam, Shukri KorakkottilProblem statement: RF MEMS switch is one of MEMS area that creates devices that have great potential to improve the performance of communication circuits and systems and enables the realization of micro size mechanical switches embedded in electronics devices. The low voltage switches are necessary due to their compatibility of standard IC technology in RF application and microelectronics systems. In … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,718 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Bone Properties due to Skeletal Diseases on Stability of Cementless Hip StemsMohammed Rafiq Abdul Kadir, Nazri KamsahProblem statement: There are two types of implant fixation in hip joint replacement-cemented and cementless. The cemented types are, in general, more popular due to concerns of possible inability of cementless implants achieving maximum primary stability for bone integration. The concern is more significant in cases where there are major losses of cancellous bone stock and thinning of the trabeculae … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,171 accessesView PDFCite
Research ArticleOpen accessIn the abstractInterface Micromotion of Cementless Hip Stems in Simulated Hip ArthroplastyMohammed Rafiq Abdul Kadir, Nazri KamsahProblem statement: The design of hip prostheses has evolved over time due to various complications found after hip replacement surgery. The currently commercially available cementless femoral stems can be categorized into one of three major types, straight cylindrical, tapered rectangular and anatomical. Each type proposes a unique concept to achieve primary stability-a major requirement for bone healing process. Virtual analyses … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of the Crack Propagation for Solid MaterialsMiloud Souiyah, A. Muchtar, Abdulnaser Alshoaibi, A. K. AriffinProblem statement: The use of fracture mechanics techniques in the assessment of performance and reliability of structure is on increase and the prediction of crack propagation in structure play important part. The finite element method is widely used for the evaluation of SIF for various types of crack configurations. Source code program of two-dimensional finite element model had been developed, … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Surface Treatment on Fatigue Life of Cylinder Block for Linear Engine using Frequency Response ApproachM. M. Rahman, A. K. Ariffin, S. Abdullah et al.Objectives: This study was focused on the finite element techniques to investigate the effect of surface treatment on the fatigue life of the vibrating cylinder block for new two-stroke free piston engine using random loading conditions. Motivation: An understanding of the effects related to the random loading is necessary to improve the ability of designers to accurately predict the fatigue … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Efficient Finite Element Software of Crack Propagation Simulation using Adaptive Mesh StrategyAbdulnaser M. Alshoaibi, A. K. Ariffin, M. N. AlmaghrabiThe purpose of this study is on the determination of 2D crack paths and surfaces as well as on the evaluation of the stress intensity factors as a part of the damage tolerant assessment. Problem statement: The evaluation of SIFs and crack tip singular stresses for arbitrary fracture structure are a challenging problem, involving the calculation of the crack path … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,830 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 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 · 8,196 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 · 7,168 accessesView PDFCite
