Comparative study of buckling behavior of generally laminated composite plates using GDQ Rules and Rayleigh-Ritz method

Abstract

Due to the importance of buckling analysis of composite structures in different branches of industry a comparative study of buckling behavior of composite plates is presented in here. Mathematical modeling developed in the present work for generally laminated plates are based on GDQR and R-R method. To show the ability and robustness of the mathematical modeling in handling buckling analysis, results obtained from GDQR and R-R are compared with each other and some available results based on experimental and analytical works. The efficiency and reliability of the GDQR in comparison with R-R method on the buckling behavior is also discussed. © 2010 by Nova Science Publishers, Inc. All rights reserved.
