The integrally stiffened shells possess the advantages of high specific strength, high specific
rigidity and excellent sealing performance, which have been widely used in the load …

Compared to straight fiber path laminates, variable-angle tow (VAT) laminates are known to
redistribute the in-plane stress resultants for improving structural buckling response. The …

On the basis of the first order shear deformation and Timoshenko beam theories, a general
Nitsche-based isogeometric analysis (IGA) is developed for studying the free vibration …

Variable angle tow laminates (VAT) and stiffeners are known to redistribute the in-plane load
distribution and tailor the buckling mode shapes, respectively, for improving structural …

This paper presents results from thermal buckling analysis and optimization of stiffened
composite panels with variable angle tow (VAT) laminates and curvilinear stiffeners …

A semi-analytical method is developed for the analysis of composite stiffened panels, where
stiffness variability is achieved through a combination of fiber steering and curvilinear …

Undevelopable stiffened curved shells have been widely used in engineering fields. The
shape of the undevelopable curved surface is generally characterized with the non-straight …

Variable stiffness composite structures offer more flexible design space than thin-walled
metal structures and have greater potential for vibration-resistant design. When faced with …

In this research, a unified computational framework was developed to analyze the complex
multiple buckling modes of stiffened cylindrical shells under hydrostatic pressure, and avoid …

A review of the literature reveals a dearth of research on the maximisation of natural
frequencies of laminated composite stiffened panels. The present study combines an …
