| Abstract: | On the basis of the shadow moire' method with curved grating , the buckling parameters such as the smallest critical load, ultimate buckling load and the buckling mode of two kinds of models of aircraft shell under the action of axial compression or uniform internal pressure were given in this paper.The two kinds of models included circular cylindrical and pillow cylindrical shells.There were twenty-eight specimens with different thickness and rib styles. |
