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 abstractNumerical Modeling of Laterally Loaded PilesS.T. Kok, Bujang B.K. HuatDesign of laterally loaded piles due to soil movement relies on a number of theoretical and numerical approaches. However, the magnitude of soil movement is difficult to estimate with reasonable confidence and accuracy. Finite Element Analysis (FEA) offers an excellent alternative to study pile-soil interaction and pile’s response under lateral loading due to soil movement. This research presents published analytical … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Stress Analysis of the Arterial Wall Utilizing Physiological Pressure WaveformsM.M. Khani, M. Tafazzoli-Shadpour, S. Delavarpour et al.Arterial diseases, promoted by alterations in arterial wall properties, are among the main causes of mortality. Mechanical stresses of the arterial wall caused by pulsatile luminal pressure define arterial function in normal and pathological conditions. This study aims to determine dynamic stress distribution in the arterial wall subjected to physiological pressure waveforms. Finite element models of a typical artery are … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,167 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Boundary Conditions on the Behavior of an Anchored Reinforced Earth WallFaisal Hj Ali, Bujang B.K. Huat, Lee Chee HaiThe finite element model is used to simulate the behavior of the full scale instrumented anchored reinforced wall. The validated finite element model is then used to carry out parametric studies to ascertain the influence of the boundary conditions on the behavior of the wall. The boundaries at the crest, facing and base of the wall are varied to study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,034 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 abstractEstimation of C*-Integral for Radial Cracks in Annular Discs under Constant Angular Velocity and Internal PressureA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral for single and double-edge cracks in eight annular rotating discs under constant angular velocity with and without internal pressure. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power law creeping finite element analyses have been performed and the results are … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,724 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 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Convective Heat-Transfer Coefficient in a Buried ExchangerTaoufik Mnasri, Rached Ben Younès, Maher Raddaoui, Salem ElouraginiThis study presents analytical models allowing to study a forced convection laminar flow in non-established dynamic and thermic regimes. We treated a flow in a bitubular exchanger in permanent thermal contact with a semi-infinite medium, such as the ground. The wall temperature as well as the wall heat flux evolve in the course of time until a quasi-steady mode. The … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,903 accessesView PDFCite
