The present work sets forth the expressions for the stresses and strains in a sandwich shell of arbitrary shape under thermal and pressure loads.
The composite shell is made of two elastic face lawers with a viscoelastic core. The elastic facings are isotropic of the same material and obey the kirchhoff hypotesis. The viscoelastic core is assumed to be thermorheologically simple as a way to facilitate the mathematical representation of the creep modulus on temperature.
In order to simplify the derivations of the needed equations it is assumed that the stresses in the core acting in the tangencial directions are much smaller than those developed in the facing, so that theycan be neglected.
The general equations for the stresses and strains are written using curvilinear shell coordinates and some results are then shown for cylindrical and conical shell geometries.
