The review surveys various modeling approaches for multilayered composite plates. The paper outlines future research directions for modeling multilayered composite plates. The study compares six two‑dimensional shear deformation theories, classified by displacement, strain, or stress assumptions, against exact three‑dimensional elasticity solutions. Numerical results demonstrate how lamination and geometric variations affect the accuracy of static and vibrational predictions from these six shear deformation theories.
A review is made of the different approaches used for modeling multilayered composite plates. Discussion focuses on different approaches for developing two-dimensional shear deformation theories; classification of two-dimensional theories based on introducing plausible displacement, strain and/or stress assumptions in the thickness direction; and first-order shear deformation theories based on linear displacement assumptions in the thickness coordinate. Extensive numerical results are presented showing the effects of variation in the lamination and geometric parameters of simply supported composite plates on the accuracy of the static and vibrational responses predicted by six different modeling approaches (based on two-dimensional shear deformation theories). The standard of comparison is taken to be the exact three-dimensional elasticity solutions. Some of the future directions for research on the modeling of multilayered composite plates are outlined.
