Analytical models and solutions are formulated and developed for the static responses of cross ply smart laminated shells with shear piezoelectric actuators. The models are based on a rigorous first-order shell theory. The state-space approach is used to find exact solutions for the static responses of cross ply spherical, cylindrical and doubly curved shells with various boundary conditions. The smart shells possess two parallel edges simply supported and the remaining ones having any possible combination of boundary conditions: free, clamped or simply supported. Deflections of cross ply laminated shells incorporating shear piezoelectric layers are determined. Numerical results for six layer laminates are generated to investigate the shells' static behavior. The exact solutions for deflections can be used as benchmarks for approximate solutions such as Rayleigh-Ritz and finite element methods.
