Improved postbuckling simulation for design of fibre composite stiffened fuselage structures (POSICOSS)

Objective

To reduce aircraft weight by 20%, without prejudice to costs and safety, an actual demand emphasised by industry is to design fibre composite fuselage structures for post buckling under ultimate load. Improved simulation tools and new design procedures for stiffened panels are needed. The project will develop them ready for industrial application, reducing design and analysis time by an order of magnitude. Industry contributes experience with design and manufacture of real shells, whereas research complementarily brings in mainly knowledge on testing and on development of simulation tools. Results are checked by industry, the final design guidelines are defined in common. Post buckling experience from 2 member and 2 associated countries is exchanged and exploited together. The results comprise substantially increased experimental databases on material properties and post buckling as well as fast, reliable software and design guidelines.
