A novel unified framework of higher-order shear deformation theories is developed for modelling and analysis of laminated and functionally graded plates. The objective of this study is to (1) unify all higher order shear deformation plate theories in a unique formulation; (2) propose a new higher-order shear deformation models based on the unified plate model. The existing displacement fields in the equivalent single layer theories are classified into three categories based on the present unified method. Existing equivalent single layer plate theories are unified according to different types of transverse displacements and transverse shear strains based on the present method and several new plate theories are proposed and assessed. The Reddy shear strain function and a changeable shear function are applied to represent the distribution of transverse shear strains through the thickness of the laminated and FGM plates,. One of the new higher-order shear deformation theories is then ascertained by comparing the bending, free vibration and buckling results of composite and FGM plates with other published ones. The results show that the unified plate model can cover all existing equivalent single layer models and is able to encourage readers to search for more feasible and accurate plate theories.
