The finite strip method is developed to predict the geometrically non‐linear response of rectangular laminated plates subjected to progressive end shortening whilst initial imperfection and/or applied pressure loading are also present. The development is an extension of earlier work concerned with perfect, unpressurized laminates which have simply supported loaded ends at which lateral in‐plane expansion is either allowed freely or is prevented completely. The analysis is conducted in the contexts of classical plate theory and first‐order shear deformation plate theory, in turn. A number of applications involving both isotropic plates and laminated plates is described.
