In this article, the deformation characteristics of sinusoidally-corrugated laminated composite panels are examined under uniform and sinusoidally distributed transverse loads. The sinusoidal corrugation in laminate structure is achieved using the general curvature method. The displacement field is based on the third-order shear deformation mid-plane kinematics theory with nine degrees-of-freedom. The minimum total potential energy method is employed to obtain the governing equation. The solutions are obtained using two-dimensional finite element approximation via nine-noded isoparametric quadrilateral Lagrangian element. The convergence and comparison studies reveal the consistency and accuracy of present model. The new numerical illustrations reflect the significance of corrugation ratios, edge constraints, side-to-thickness ratios and aspect ratios on the deformation behavior of the corrugated and non-corrugated laminated composite panels.
