Project Description

Aerospace Multidisciplinarity Enabling Design Optimisation

AMEDEO is a Marie Curie Initial Training Network, bringing together leading academic researchers and key private sector partners with the aim of developing the tools needed by the European aerospace industry to design the next generation of environmentally friendly aircraft.

The project’s focus is on developing the use of Multidisciplinary Design Optimisation (MDO), a technique which has been identified by the European Commission in its report ‘Flightpath 2050’ as critical for the future sustainability of the European aerospace industry. AMEDEO will provide 13 early stage researchers with an innovative PhD training programme covering the technical skills and industrial experience they will need to become research leaders of the future.

ALE will lead one of the PhD projects and provide secondments to three other researchers, where their expertise in the design and analysis of lightweight composite structures will be vital. The lead project has the working title of ‘Delamination of composite structures using Isogeometric Analysis’. The project is motivated by the need for a more thorough understanding of the failure mechanisms of composite structures as their use becomes increasingly widespread.

The focus of the work is on modelling delamination and delamination propagation in the framework of Isogeometric Analysis (IGA), a new method in computational mechanics. IGA uses exact geometry from CAD and eliminates the need for a traditional finite element mesh which can dominate analysis time for complex models. The project includes a fictitious domain extension of IGA for laminated composites to overcome topological restrictions inherent to NURBS models. The extension allows modelling and simulation of arbitrary complex shapes, ideal for shape optimisation, whilst profiting from the smoothness and exact geometry description of NURBS.
