Research ArticleOpen accessIn the abstractThe Effect of the Configuration of the Screw Fixation on the Interfragmentary StrainBoonthum WongchaiProblem statement: The interfragmentary strain (εIF) is the important parameter for femur fracture healing. The Dynamic Compression Plate (DCP) is commonly used in femur fracture. The DCP and the fractured femur are fixed by using the conventional screws. Approach: This research is proposed to investigate the effect of configuration of the screw fixation on the interfragmentary stain by using Finite … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 15 Mar 2012 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simplified Two-Dimentional Unit Cell Model for Analyzing the Transverse Shear Stiffness of Three-Dimentional Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a complex three-dimensional model affects the speed of calculation time. A simplified two-dimensional model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents a study on the analysis of the transverse shear stiffness of three-dimensional truss-like core sandwich beam using a simplified two-dimensional unit … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Elastic-Plastic Contact Performance of Rigid Sphere Against a Deformable Flat-Effect of Strain HardnessV.C. Sathish Gandhi, S. Ramesh, R. KumaravelanProblem statement: The present study considers an elastic-plastic contact analysis of a rigid sphere with a deformable flat (Rigid Sphere-model) using finite element analysis. The effect of tangent modulus on the contact behavior of a no adhesive frictionless elastic-plastic contact was analyzed using commercial finite element software ANSYS. Approach: Different materials, in terms of the ratio of Young's modulus to … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 8,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability and Ergonomic Design Features of Tractor Mounted Hydraulic Elevator for Coconut HarvestingKishor Purushottamrao Kolhe, Ashok G. Powar, Amit D. Dhakane, Sham H. MankarProblem statement: The most important design criterion of mechanized device was safety; safety comprises both the safety of operator and safety of maintenance personnel. Failures and safety of harvesting platform of Tractor Mounted Hydraulic Elevator (TMHE) powered by tractor PTO was tested by finite element method for the mechanical harvesting of coconut orchards using digital ergonomic hart rate meter. The … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 20 Sep 2011 · 8,335 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress Prediction in the Dynamic Compression Plate with Changing the Configuration of the Screw FixationBoonthum WongchaiProblem statement: Human femur fracture is one of the most frequent type of bone fractures. One of the widely used methods in an internal fixation is an application of the Dynamic Compression Plate (DCP). The configuration of the screw fixation plays a major role of the DCP stress. Approach: This research is proposed to investigate the stress distribution in the … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Cycle Duration and Phasing on Thermomechanical Fatigue of Dog-Bone Specimens Made form SteelAchegaf Zineb, Khamlichi Abdellatif, Francisco Mata CabreraProblem statement: Lifetime of standard dog-bone specimens made form steel as affected by phasing between thermal cycles and strains cycles and by cycle duration in thermomechanical fatigue is assessed under various conditions of loading. Approach: The methodology used was based on finite element post-processing analysis by specialized fatigue software package that takes into account coupling of damage from three primary … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 7,700 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress-Strain Analysis of Abdominal Aortic Wall: A Case of 3D Geometry SimulationP. Khamdaengyodtai, P. Sakulchangsatjatai, P. TerdtoonProblem statement: This study analyzed stress-strain of abdominal aortic wall in 3D geometry simulation. Abdominal aorta is a portion of the aorta vessel in the abdomen which many cardiovascular diseases often occur. Approach: Abdominal aortic wall was considered as 1 layers-3 dimensional cylindrical geometry and homogeneous, incompressible and anisotropic material. Deformation of aortic wall was elastic deformation. Numerical method was … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Connection Simulation Using Dynamic Nodal Numbering AlgorithmAlongkorn Lamom, Thaksin Thepchatri, Wanchai RivepiboonProblem statement: The traditional dynamic nodal numbering algorithm was proposed for generating code number to support truss and frame simulation using only one element type, frame element; it facilitates the software development process. The traditional algorithm, however, supports simulation of only two types of connection: Hinged connection and rigid connection. In many cases, the problems consist of mix-connection and hybrid … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Two Interacting Localized Defects on the Critical Load for Thin Cylindrical Shells Under Axial CompressionAbdellatif Khamlichi, Jalal El Bahaoui, Larbi El Bakkali et al.Problem statement: Many modern structures are made from thin shells. Design of these elements depends to a large extent on their buckling behavior which is hugely affected by the initial geometric imperfections. Approach: For axially compressed isotropic circular cylindrical shells, axisymmetric localized geometric imperfections were found to reduce severely the buckling strength. Among various axisymmetric shapes of localized defects that … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,073 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Modeling of Transient Temperatures in a Small-Caliber ProjectileM. Brian Thomas, Leon DozierProblem statement: Future generations of intelligent munitions will use Microelectromechanical Systems (MEMS) for guidance, fuzing logic and assessment of the battlefield environment. The temperatures fund in a gun system, however, are sufficient to damage some materials used in the fabrication of MEMS. The motivation of this study is to model the dynamic temperature distribution in a typical small-caliber projectile.
