WitrynaMedium length shells are studied, of equally elastic and isotropic material and of different dimensions. Given that geometric imperfections are viewed as a main source of imperfection sensitivity, their magnitudes are adjusted for individual shells by a previously introduced energy measure. 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.

Witryna31 sie 2005 · The paper deals with the perturbation energy concept and its application to stability of imperfection sensitive structures under time-dependent loads. The evaluation of the stability is based on energy norms, which may be used for investigation of safety against buckling. Witryna17 sty 2024 · Past studies have demonstrated the effectiveness of wavy cylinders to reduce imperfection sensitivity of thin cylinders under axial compression assuming linear elastic material behavior. These studies used eigenmode imperfections which do not represent realistic imperfections found in cylinders.
