Abstract

This work is concerned with a two-dimensional finite element study of the transient response of laminated thin circular cylindrical shell panels subjected to thermal impact under the framework of linear coupled thermoelasticity. A nine-node isoparametric element is applied to the FEM formulation. Numerous examples are given, in which the shell panels are assumed to be thermally isolated at four edges and the bottom surfaces and a heat flux is then imposed suddenly on their top surfaces. The effects of boundary conditions, ply-angles and radii of curvature are discussed. In addition, the differences between uncoupled and coupled problems are especially addressed.
