A new high-order refined shear deformation theory based on Reissner's
mixed variational principle in conjunction with the state- space conce
pt is used to determine the deflections and stresses for rectangular c
ross-ply composite plates. A zig-zag shaped function and Legendre poly
nomials are introduced to approximate the in-plane displacement distri
butions across the plate thickness. Numerical results are presented wi
th different edge conditions, aspect ratios, lamination schemes and lo
adings. A comparison with the exact solutions obtained by Pagano and t
he results by Khdeir indicates that the present theory accurately esti
mates the in-plane responses.
