  Today, Flapping Micro Aerial Vehicles (MAV) are used in many different applications. Reynolds Number for this kind of aerial vehicle is about 104 ~ 105 which shows dominancy of inertial effects in comparison of viscous effects in flow field except adjacent of the solid boundaries. Due to periodic flapping ...  Read More

Compressional Stability Behavior of Composite Plates with Multiple Through-the-Width Delaminations

H.R. Ovesy

Volume 5, Issue 1 , March 2008, Pages 13-22

  In this paper, the compressive behavior of composite laminates with multiple through-the-width delaminations is investigated analytically. The analytical method is based on the CLPT theory and its formulation is developed on the basis of the Rayleigh-Ritz approximation technique to analyze the buckling ...  Read More

Numerical Simulation of Partial Cavitation over Axisymmetric Bodies: VOF Method vs. Potential Flow Theory

Mohammad Pasandidefard Fard

Volume 5, Issue 1 , March 2008, Pages 23-33

  A computational study of partial cavitation over axisymmetric bodies is presented using two numerical methods. The first method is based on the VOF technique where transient 2D Navier-Stokes equations are solved along with an equation to track the cavity interface. Next, the steady boundary element method ...  Read More

The Effects of Shape Parameterization on the Efficiency of Evolutionary Design Optimization for Viscous Transonic Airfoils

Ava Shahrokhi; Alireza Jahangirian

Volume 5, Issue 1 , March 2008, Pages 35-43

  The effect of airfoil shape parameterization on optimum design and its influence on the convergence of the evolutionary optimization process is presented. Three popular airfoil parametric methods including PARSEC, Sobieczky and B-Spline (Bezier curve) are studied and their efficiency and results are ...  Read More

U-Bending Analysis with an Emphasis on Influence of Hardening Models

M. Kadkhodayan

Volume 5, Issue 1 , March 2008, Pages 45-50

  In this paper the effect of different hardening models in simulating the U-bending process for AA5754-O and DP-Steel, taking a benchmark of NUMISHEET 93 2-D draw bending, has been discussed. The hardening models considered in simulations are: isotropic hardening, pure (linear) kinematic hardening and ...  Read More
