Buckling of laminated plates subjected to non-uniform distributed in-plane force

Abstract

The buckling and vibration of laminated plates with various types of non-uniform compressive edge loads is analyzed. This problem requires that first the elasticity problem be considered to obtain the distribution of in-plane stresses, and after that, the buckling problem is solved. The method of solution is based on the R-functions theory and the variational Rayleigh-Ritz method. The results are compared with the results obtained by other authors to confirm the reliability of the method. The behavior of a complex form plate with a cutout has been investigated.
