1. Buckling Analysis of Rectangular Laminated Composite Plates With An Edge Delamination Under Compressive Load

Mohammad Ali Kouchakzadeh

Volume 4, Issue 1 , Winter and Spring 2007, Pages 1-8

Abstract
  The buckling analysis of rectangular laminated composite plates with an edge delamination under in-plane compressive loading is performed using the finite element method. Such a plate may be considered as a simplified model of stiffener plates of a stiffened panel. The buckling load and buckling mode ...  Read More

2. NUMERICAL ANALYSIS OF THE INFLUENCE OF STOPPING HOLES IN THE CRACK GROWTH

M. R. Khoshravan; A. Hamidi

Volume 4, Issue 1 , Winter and Spring 2007, Pages 9-16

Abstract
  The fracture and crack growth of mechanical structures is a usual phenomenon which is due to the application of tensile, cyclic loading or thermal stresses on the structure. So introducing of methods to prevent the crack growth is useful. Afterward, one of the repairing methods of crack growth, consisting ...  Read More

3. A Message-Passing Distributed Memory Parallel Algorithm for a Dual-Code Thin Layer, Parabolized Navier-Stokes Solver

o. Abouali

Volume 4, Issue 1 , Winter and Spring 2007, Pages 17-23

Abstract
  In this study, the results of parallelization of a 3-D dual code (Thin Layer, Parabolized Navier-Stokes solver) for solving supersonic turbulent flow around body and wing-body combinations are presented. As a serial code, TLNS solver is very time consuming and takes a large part of memory due to the ...  Read More

4. Damage Assessment using an Inverse Fracture Mechanics approach

F. Javidrad

Volume 4, Issue 1 , Winter and Spring 2007, Pages 25-32

Abstract
  This paper studies the application of an inverse methodology for problem solving in fracture mechanics using the finite element analysis. The method was applied to both detection of subsurface cracks and the study of propagating cracks. The procedure for detection of subsurface cracks uses a first order ...  Read More

5. INVESTIGATION OF PRELOAD EFFECTS ON NONCIRCULAR GAS BEARING SYSTEMS PERFORMANCE

Asghar Dashti Rahmatabadi

Volume 4, Issue 1 , Winter and Spring 2007, Pages 33-38

Abstract
  This paper presents the effect of preload on static and dynamic performance characteristics of several gas-lubricated noncircular journal bearing configurations. The linearized system approach using finite element method is used to obtain both steady state and dynamic characteristics. The results of ...  Read More

6. Numerical Investigation of Rotating-Stall in a Stage of an Axial Compressor with Two Different Approaches

B. Farhanieh

Volume 4, Issue 1 , Winter and Spring 2007, Pages 39-47

Abstract
  An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters and the two-layer Baldwin-Lomax turbulence model was also implemented. To validate the solver, two test ...  Read More
