Snap-Buckling of Dished Shallow Shells under Uniform Loads
-
Abstract: A theoretical analysis is presented for the snap-buckling behaviour of dished shallow shells under undorm loads. By means of the modified iteration method, the second approximate formula of elastic behaviour and a set of numerical solutions aregiven. And effects of parameters β and k on the snap-buckling behaviour are discussed.
