Keywords: torsion, postbuckling, metamodelling, damage tolerant structures

The research here presented regards the development of an optimization technique for the design of damage-tolerant stiffened composite structures subjected to combined compression and shear loading. The proposed methodology wants to satisfy a number of different performance requirements, such as buckling load and post-buckling stiffness for various states of damage.
