Project description
Making aerostructures able to switch among stable shapes with high fatigue performance
Multi-stable composite structures hold great potential for creating adaptive aerospace designs that reduce fuel consumption. However, achieving both multi-stability and the stiffness needed to carry loads is challenging, and repeated stable-mode switches can lead to fatigue damage. With the support of the Marie Skłodowska-Curie Actions programme, the DEFORM project plans to design next-generation aerospace structures exhibiting both multi-stability and high fatigue resistance. Using an innovative three-phase framework, DEFORM will develop tailored layup configurations for sequential buckling design, advanced fatigue damage modelling for non-linearly large deformation, and real-time damage diagnostics for structural-level assessment. The proposed work will push the boundaries of aerospace design, enabling more efficient and durable composite structures for the future.
Objective
Multi-stable composite structures are promising candidates to create adaptive/morphing structures and decrease fuel consumption for aerospace sectors. However, it seems to be a paradox to allow structures being multi-stable and stiff enough to carry loads simultaneously. Repetitive stable-mode switches also cause fatigue damage onset.
To support EU aviation emission cut by 2050, DEFORM will deliver a cutting-edge design of next-generation aerospace structures exhibiting both multi-stability and high fatigue performance. Current knowledge gaps are: whether we can modify existing aerospace structures to become multi-stable; how their fatigue damage accumulates under non-linearly large deformation. DEFORM will use a three-phase interdisciplinary framework to fill in the gaps. Phase 1: Tailor non-uniform thermal stress distribution to create sequential-buckling-driven multi-stability for stiffened aerospace composite structures that can perform three stable modes under varying load amplitudes. Phase 2: Implant buckling-mode switch analysis into a virtual-crack-closure-technique-based algorithm for efficient fatigue damage modelling, providing dataset to optimise a down-scaled demonstrator with extended fatigue life and increased fatigue damage resistance. Phase 3: Perform multi-field interactive damage diagnostics in real time to measure optical-acoustic-mechanical properties at a structural level, for evaluation of fatigue damage accumulation scheme of composite structures under repetitive stable-mode switches.
Overall, DEFORM will advance state-of-art of against-fatigue design, modelling and testing for multi-stable aerospace structures beyond the known limits, supporting European Green Deal for the EU’s ambition of climate neutral by 2050.
