How do advanced composite materials perform after millions of load cycles in the demanding environment of an aeroengine? As a doctoral student in this international research collaboration, you will help answer that question through a combination of experimental testing, advanced simulations, and close interaction with leading researchers and industry experts. Your work will contribute to the development of future aerospace structures that are lighter, more efficient, and more reliable.
About UsThe PhD position is placed at the Division of Computational Mechanics and Materials Engineering. We foster an inclusive, friendly, and helpful work environment to which we welcome you to contribute. Our activities integrate computational mechanics and advanced materials technology, combining multidisciplinary expertise to predict, understand, and elevate the performance of engineering materials and structures.
Within the project, you will be supported by an international team of experts in the area of mechanics of composites, combining academic excellence with industrial expertise and experience.
About The Research ProjectThe project aims to enable the deployment of advanced composite structures in aeroengines by developing reliable methods for predicting fatigue life of textile carbon fibre composites under thermomechanical tension-tension loading. Through combined experimental characterisation and development of an industrially applicable simulation framework, the project will support safe and efficient design of complex aerospace components.
More Specifically, The Project Goals Are To
- Characterise the fatigue properties and stiffness degradation of a relevant prototype textile reinforced composite material system under pure cyclic tension-tension loading.
- Develop an industrially applicable and computationally efficient ply-level macroscale fatigue model that describes how damage evolves under varying load amplitudes and thermal conditions.
- Combine the novel ply-level fatigue model with an existing state-of-the-art inter-laminar fatigue damage model into a complete fatigue life assessment framework.
- Accelerate the computational efficiency of the framework by utilising novel cycle extrapolation techniques to represent the effect of fatigue loading over many cycles at a time.
- Evaluate realistic but critical thermomechanical fatigue cycles through a combined experimental-simulation approach.
- Enable industrial adoption of the proposed fatigue assessment framework into future design procedures at GKN Aerospace.
