A general higher-order approximation theory for analysis of static and/or dynamic behavior of laminated composite structures with interlayer slip is developed. Theoretical characteristics and validity of the theory are clarified using numerical examples. The theory is formulated by using a modified Hamilton's principle with relaxed displacement continuity requirements, after expanding displacements of each lamina using power series of the thickness coordinate. The independent unknown variables of this theory are the displacement coefficients of each lamina and interlamina stresses. It is shown that the present theory includes so many previous theories, and overcomes the defects of those theories.
