Study of Aspect Ratio Effect on Mechanical Properties Polymer/NanoComposite
(Islamic Azad University, Khomeinishahr Branch, 2011-09-01)Carbon nanotubes (CNTs) demonstrate unusually high stiffness, strength and resilience, and are therefore an ideal reinforcing material for nanocomposites. However, much work has to be done before the potentials of CNT-based ...

Investigation of Important Parameters in Residual Stress Determination in Isotropic Plates and Laminated Composites by Slitting Method
(Islamic Azad University, Khomeinishahr Branch, 2011-09-01)In the slitting method, a small width slit is created incrementally through the thickness of the stressed specimen and the released strains in each increment are recorded by a strain gauge. Compliance coefficients relate ...
