On the axisymmetric post-buckling of a thin elastic circular plate under uniform edge pressure

Abstract

In this paper, we revised a post-buckling of an elastic circular plate subject to uniform pressure on its edge. The governing von Karman equations are solved by power series method and numerical colocation method. An alternative method for calculation of coefficients of the series solution is described. It is shown that the power series solution is useful only for the first buckling mode while collocation method can handle also higher buckling modes.
