This paper presents a comprehensive review of the theories and finite element formulations for laminated composite plates and shells. The classical and higher order shear deformation theories and their various refinements, merits and drawbacks are discussed. A detailed discussion of the piece-wise lamina or layer-wise theories is also presented. It is demonstrated that both higher order shear deformation theories and piece-wise lamina theories can be easily utilized to develop hierarchical finite element formulations for laminated plates and shells. These hierarchical formulations include the transverse normal strains necessary for thick composite laminates. Numerical examples are presented to demonstrate the effectiveness of hierarchical formulations based on the equivalent single-layer and piece-wise or layer-wise concepts.
