Twist morphing concept based on buckling-driven technologies

A novel twist morphing concept is explored, that exploits the buckling instabilities of slender spar webs integrated into a wing structure to control the twisting response to external loads. The main novelty of the concept is in controlling the effective shear stiffness of the post-buckled slender spar webs through external variable constraints...

Development of a Finite Element based Strength Calculation method for Curved Composite Laminates

An accurate corner strength modelling method is required at Fokker Aerostructures to design canisters (missile launch tubes) with rounded corners for an internal pressure load case. To this end a combination of experiments and calculation methods has been developed that enable to predict the corner strength more accurately. Internal pressure...
