Imperfections from manufacturing process can cause a scattered reduction of the load-
carrying capacity or buckling load of axially compressed cylindrical shell structures. To …

For cylindrical shells under axial compression, the essence of initial geometric imperfections
is the superposition of local out-of-plane deformations of various forms, which may facilitate …

Stiffened shells in launch vehicles are very sensitive to various forms of imperfections. In this
study, the imperfection sensitivity of a 4.5 m diam isogrid stiffened shell under axial …

A currently used guideline for cylinder structures under axial compression is the NASA SP-
8007 which is based on empirical data from the 1960s. This guideline provides knock-down …

Thin-walled cylindrical shells are primary structures in aerospace, marine and civil
engineering. A major loading scenario for these imperfection sensitive shells is axial …

In this paper a physically based and deterministic design procedure for spherical shells
under external pressure is introduced. Within the new design concept the membrane energy …

This paper overviews the efforts that led to new improved knockdown factors for the design
of cylindrical shells under axial compression. The corresponding design methods were …

This article contains examples to demonstrate the use of different design concepts for
cylindrical shells under axial compression. The examples are based on shells which were …

Variable-stiffness (VS) laminated shells with curved fibers have gradually become a
promising lightweight structural concept in the aerospace field. However, as the complexity …

The stability failure of the axially loaded cylindrical shell is considered as the last unresolved
classical stability problem, although it has been investigated for over 100 years. Therefore …
