Abstract

The reliability of imperfection-sensitive shells is derived. The Koiter (asymmetric case) formula is used to construct the failure criterion for the case where the imperfection surface is described by two terms of a double Fourier series with random amplitudes. The effect of the correlation between these variables is also investigated. In some cases exact solutions are derived, while in others, approximate derivations are obtained within the Hasofer-Lind method.
