1. Numerical and Analytical Investigation of the Sandwich sheet Rolling Process ConsideringCoulomb Friction

Vali Alimirzaloo

Volume 8, Issue 3 , September 2015

Abstract
  Sandwich sheet rolling process is investigated using an analytical method (slab method) and a numerical method (finite element method). The horizontal stress distribution in the layers, the rolling pressure along the contact interface and the neutral point between the roll and the sheet are investigated. ...  Read More

4. An investigation of Reynolds number effect on the aerodynamics of bluff body with sharp edges

Amir Bak Khoshnevis; Amir Reza Mamouri; Farzad Mir

Volume 8, Issue 3 , September 2015

Abstract
  In general, the aerodynamic stability of long span bridges is evaluated based on the results of wind tunnel tests in the low Reynolds number region, because in almost all wind tunnel tests, it is impracticable to satisfy Reynolds number similitude. Therefore, in order to correctly evaluate conventional ...  Read More

5. Effects of baffle on separated convection step flow of radiating gas in a duct
