Abstract
The higher order shear deformation plate theory is used as a basis for development of the family of enhanced finite plate elements. The proposed single layered higher order discrete models allows a parabolic distribution of shear strains through the plate thickness as well as a cubic variation of in-plane displacements. Numerical solutions obtained using new finite elements in static, dynamic, free vibration and buckling analysis are compared with solutions based on three-dimensional, classical and first order shear deformation plate theories and it is demonstrated that the present model predicts a realistic laminate global response. The new results for composite plates should serve as bench marks for future investigations. 1 Introduc
