Abstract: Weak formulation of mixed state equation and boundary condition for axisymmetric cylindrical shell are presented in a cylindrical coordinate system by introducing Hellinger- Reissner variational principle.  Analytical solution are obtained for laminated cylindrical shell by means of state space method.  The present study extends and unifies solution of  laminated  shell.
Keywords: mixed state equation, state space, axisymmetric cylindrical shell, weak formulation, boundary problem.
