Imperfection sensitivity
Witrynacal/distortional/overall mode interaction and also sensitivity to imperfections of thin–walled cold–formed steel members. Loughlan et al. [16] analysed the … Witryna1 cze 2024 · This article covers the imperfection sensitivity and design of tori-spherical domes under external pressure. In the second section of this article a numerical model and experimental results of a tori-sphere are presented. The third section presents different numerical design concept for tori-spherical shells.

WitrynaThe analysis can be the first step in a global analysis of an unloaded structure, or it can be performed after the structure has been preloaded. It can be used to model measured initial overall and local geometric imperfections or in the investigation of the imperfection sensitivity of a structure in case of lack of measurements. WitrynaWang et al. 16 studied the imperfection sensitivity of an isogrid-stiffened shell under axial compression, and they found that the dimple-shaped imperfection approach …

An eigenvalue buckling analysis will not give accurate predictions of the buckling load for imperfection-sensitive structures; the static Riks procedure should be used instead (see “ Unstable collapse and postbuckling analysis ...
