Abstract

The axisymmetric linear quasi-static thermoelastic equations for composite orthotropic cylindrical shells are solved in closed form for fixed-end boundary conditions.The case of semi-infinite shell is explicitly evaluated and various combinations of laminated shells are examined. It is shown that 1.(1) shell heterogeneity, or the layer reversal effect for two-layer shells, may significantly affect the stress field obtained and its level;2.(2) the combined action of the composed layers transcends the sum of the individual properties and provides, in many cases, new performance unattainable by the constituents when acting as homogeneous shells;3.(3) a cross-thermoelastic effect is exhibited by the stress distribution for the considered composite shells.
