Topology optimization was developed as an advanced structural design methodology to
generate innovative lightweight and high-performance configurations that are difficult to …

Owing to their high strengths and stiffnesses, carbon fibre reinforced composites (CFRC) are
widely used in aerospace engineering for lightweight structural designs. The introduction of …

The important role of geometric imperfections on the decrease of the buckling load for thin-
walled cylinders had been recognized already by the first authors investigating the …

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

Thin-walled cylindrical shell structure not only shows the highly efficient load carrying
capacity but also is vulnerable to buckling instability failure. In practical application, these …

In the field of aerospace engineering but also in the fields of civil and mechanical
engineering the industry demands for significantly reduced costs for development and …

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 …

Launch-vehicle primary structures like cylindrical shells are increasingly being built as
monolithic composite and sandwich composite shells. These imperfection sensitive shells …

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 …

This paper presents numerical results focusing on the buckling behaviour of externally
pressurised imperfect spherical shells. The numerical model followed the recommendations …
