Dynamic analysis of clamped laminated curved panels

Abstract

The free vibration and dynamic response of clamped laminated curved panels subjected to the step, triangular and explosive loadings are investigated. The case of rectangular panels having fixed boundary conditions is also considered. The Rayleigh-Ritz method is employed to obtain the natural frequencies of the clamped laminated curved panels by using a set of simple polynomials as admissible functions. The normal mode superposition method is then used in the analysis of the dynamic response. Numerical results of the symmetric angleply, symmetric and antisymmetric cross-ply laminated curved panels under three kinds of dynamic loadings are presented. © 1995.
