The aim of this project is to create new topology optimisation methods for the design of composite lightweight stiffened shell structures.
Stiffened shell structures are used in many industries to provide lightweight solutions in mass critical designs,
such as aircraft wings and fuselage, wind turbines, bridge decks and ship hulls. However, they are complex to design, as their structural performance is dependent on many interconnected variables, such as stiffener layout, number, thickness, and type. Further complexity is introduced when using composite materials, like carbon fibre reinforced polymer.
Topology optimisation is a powerful design approach where the size, shape and layout of a structure are optimised simultaneously, leading to highly efficient novel designs. This approach has been applied to optimise stiffened shell structures before. However, existing methods are often limited by their design freedom and do not fully exploit the potential of topology optimisation (e.g. by fixing stiffener shape and position, fixing shell thickness, or using isotropic materials). Other methods rely on complex heuristic procedures that limit their use beyond simple design criteria and linear modelling. Thus, this project will aim to develop methods that can overcome the limitations of existing techniques, and improve the design of composite stiffened shell structures.
Selection will be made on the basis of academic merit. The successful candidate should have, or expect to obtain, a UK Honours degree at 2.1 or above (or equivalent) in Mechanical Engineering, Civil Engineering, Aerospace Engineering (or similar).
Essential knowledge of: structural mechanics, finite element analysis, computer programming.
Knowledge of: nonlinear mechanics, optimisation methods and composite materials, is desirable.
