We prove that the ultimate strength of postbuckling for simply supported rectangular composite thin plates under compression is far higher than their buckling stress through the tests of 283 rectangular composite thin laminates. In addition, we study the ultimate strength of composite thin plates by using large-deflection theory and small-deflection theory of thin plates. Finally, using the failure criterion, we find the ultimate strength explicitly. The results are in accordance with experimental values.
