3305 Buckling Analysis of Laminated Composite Shells of Revolution : Effects of Axisymmetric Initial Imperfections on Dynamic Buckling

Abstract

The finite element method is applied to the nonlinear axisymmetric dynamic buckling analysis of laminated composite shells of revolution. The coupling effect of general laminates is considered in the stress-strain relation. The effects of axisymmetric initial imperfections on the dynamic buckling pressure of shallow spherical shells are investigated.
