A general higher-order approximation theory to analyze static and/or dynamic behaviors of laminated composite structures is established. Theoretical characteristics and validity of the theory are made clear by numerical examples. The theory is formulated by using a modified Hamilton's principle for relaxed displacement continuity requirement, after expanding displacements of each lamina using power series in the thickness direction. The independent unknown variables of this theory are displacement coefficients of each lamina and interlaminar stresses. It is shown that the present theory takes account of the previous theories, and improves the inconsistencies of those theories.
