The finite element analysis of homogeneous and laminated composite plates using a simple higher order theory



The higher order shear deformation plate-bending theory introduced by Reddy and others is used as a basis for the development of two new finite elements. This higher order theory allows a parabolic distribution of transverse shear strains through the plate thickness. Solutions obtained using the new elements are compared with exact closed-form solutions based on three-dimensional, first and higher order shear deformation plate bending theories.
