ABSTRACT
Large deflections of orthotropic cylindrical shells under thermal loading has been analysed using displacement formulations. The total potential energy is obtained combining the potential energies of bending and stretching of the middle surface of the orthotropic shell along with the potential energy due to heating and the load. Displacement equations are derived from this total potential energy applying Euler’s variational principle. The in-plane displacement equations have been first solved and then the differential equation for the normal displacement has been solved by Galerkin’s technique. Central deflection parameters have been computed for different thermal loads. Results are presented in tabular form and compared with known results.
