1,2 and introducing boundary displacement functions, the state equation is established for thick laminated cylinder with clamped edges under any radial surface loads and the exact static solution is presented.

State variable method for the analysis of the dynamic response of laminated cylindrical shells with arbitrary thickness;

Thus, the theory of state space is combined with variational principles to give the variational static and dynamic solutions for thick laminated open cylindrical shell.

Based on the fundamental equations of three dimensional elasticity, and by introducing boundary displacement functions, the state equation is established for thick laminated open cylindrical shell with clamped edges subjected to arbitrary loads.

Based on the fundamental equations of thermal elasticity, the state equation for a orthotropic laminated cylinder with clamped edges under thermal loads is established by introducing state space theory.
