Sadovský, Z., Teixeira, A.P. e Guedes Soares, C. (2005), “Degradation of the Compressive Strength of Rectangular Plates due to Initial Deflection”, Twin-Walled Structures, Vol. 43, pp. 65-82

The paper addresses the problem of the influence of initial deflections on collapse strength of thin rectangular plates in longitudinal compression. Measured data on distortions of stiffened plating in ships as well as buckling and localised shapes are studied. For comparison of the strength values the initial deflections are normalised by an energy measure and by the commonly employed amplitude to thickness ratio.
