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 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 · 8,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime-Dependent Behavior of Piles under Combined LoadingsMohd Raihan Taha, Qassun S. Mohammed Shafiqu, Zamri H. Chik, Jasim M. AbbasThis study investigates time-dependent lateral response of piles in elastoplastic soils under combined axial and lateral loadings. Mohr Coulomb model representing the soil and the finite element formulation were described and verified. The transient analysis of pile problem was then carried out and the results of the analysis were presented which demonstrate the effects of the consolidation process on the … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractRBFNN Model for Predicting Nonlinear Response of Uniformly Loaded Paddle CantileverAbdullah H. AbdullahThe Radial basis Function neural network (RBFNN) model has been developed for the prediction of nonlinear response for paddle Cantilever with built-in edges and different sizes, thickness and uniform loads. Learning data was performed by using a nonlinear finite element program, incremental stages of the nonlinear finite element analysis were generated by using 25 schemes of built paddle Cantilevers with … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,645 accessesView PDFCite
Research ArticleOpen accessIn the abstractFracture and springback on Double Bulge Tube Hydro-FormingF. Djavanroodi, M. GheisaryThis research aims to establish a basic understanding of Double Bulge Tube Hydro-Form processing of stainless steel deep drawn cups. The method is briefly reviewed by carrying out experimental tests and Finite element analysis. By measuring bulge height in both formed curves by Coordinate measuring machine (CMM) and thickness variation specimen by Ulterasonic thickness measurment device (UTM), it has been … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Parameters Affecting Warping In Radial Forging ProcessF. Djavanroodi, M. Sabeghi, K. AbriniaRadial forging is a process in which one or two punches move axially causing a radial flow into a die cavity by means of which a flange is formed. During forging, warping, in which the lower face of thin flange rises from the die face may occur. To better understand the effect of parameters affecting the warping in radial forging … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,543 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 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerically Studying the Effect of Stiffening Rings on Reducing the Thickness of Torospherical Heads under Pressure on Their Concave SideSa'id Golabi, Ali Ghorbanpour-Arani, Arash ZamaniThe high thickness of heads used in pressure vessels is always one of the main concerns of designers and manufacturers. A thorough study has been conducted on all types of heads including torospherical heads, with external and internal pressure to reduce their thickness using stiffening rings by finite element technique. Here the result of analysis on heads with pressure on … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,148 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 · 7,042 accessesView PDFCite
