In order to a priori find the mode of conversion of a structure from imperfection sensitivity to insensitivity in the course of sensitivity analysis of the initial postbuckling path (cf. [2]), terms appearing in the consistently linearized eigenvalue problem (cf. [1]) are studied. Two main classes can be identified (cf. [4]). The first one is characterized by the restriction of the prebuckling deformations to axial deformations. For this class, the quality of the aforementioned conversion is better than the one for the other class, for which the above restriction does not hold. (© 2009 Wiley‐VCH Verlag GmbH & Co.
