This paper presents a critical review of analytic solutions for bending and buckling of flat, rectangular, orthotropic plates by comparing them with finite element results. Included are plates with two edges simply supported/two edges clamped, and all edges clamped. An orthotropy resealing technique is employed to simplify the analysis. The material orthotropy is characterized by two non-dimensional parameters, {lambda} = D{sub 22}/D{sub 11} and {eta} = (D{sub 12} + 2D{sub 66})/{radical}(D{sub 11}D{sub 22}). Closed-form solutions are given for the critical buckling load under in-plane compression and the maximum deflection under out-of-plane uniform pressure. It is found that solutions can be obtained directly from the corresponding isotropic results if {eta} {approx} 1. It is also found that for plates with all edges clamped, the analytic solution for critical buckling load is neither accurate nor conservative; a better solution needs to be developed for design purposes.
