Volume 5, Issue 4 , December 2008, , Pages 180-182

Abstract
  Two 2-D aeroelastic models are presented here to determine instability boundary (flutter speed) and gust response of a typical section airfoil with degrees of freedom in pitch and plunge directions. To build these 2-D aeroelastic models, two different aerodynamic theories including Indicial Aerodynamic ...  Read More

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems

Hassan Haddad Pour

Volume 3, Issue 2 , June 2006, , Pages 105-111

Abstract
  The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons ...  Read More
