Modelling the response of soft membranes for lightweight structures in extreme conditions
Structural membranes are widely used in engineering due to their ability to undergo large deformations, with applications ranging from civil constructions (e.g. inflatable roof stadium) to advanced aerospace systems (e.g. NASA Superpressure Balloons and membrane antennas), and including biomedical devices, soft robotics, stretchable electronics, and tissue engineering. Although these thin films are extremely lightweight, with submillimeter thickness and low areal density, they can withstand severe thermal and mechanical loading conditions. However, the highly deformable solids employed in these lightweight membrane structures are difﬁcult to characterise and control, thus limiting the long-term response and the life of the engineered systems.
The project aims to predict the behaviour of soft membranes under a wide range of thermal and mechanical loading conditions through the development of advanced and accurate nonlinear constitutive models. In particular, a major task will be to develop a reliable method to assess the (visco)elastoplastic transition in inflatable thin films constituted of different structural materials, mainly for aerospace applications. Advanced mathematical modelling of solid mechanics and numerical simulations (finite element method) will be employed to establish constitutive relations and evaluate systems performances. A variety of experimental tests will be designed and conducted throughout the entire project to characterise and validate the material and the structural responses. Experiments will include the use of electromechanical testing machine, digital image correlation technique, inflatable test boxes, and environmental chamber.
The successful candidate will have the opportunity to gain experience and contribute to the development of new theoretical, numerical and experimental research methods. As a PhD student at UCL you will benefit from mechanical engineering research training, high-performance computing, and experimental laboratories. Furthermore, you will be encouraged to publish your work in leading peer-reviewed journals and present your findings at the most important national and international conferences.
Applicants must have a UK-equivalent first degree in solid mechanics, structural/mechanical/materials engineering or a related discipline. Experience with material and structural modelling, experimental characterisation, and numerical simulations is a significant advantage. Excellent organisational, interpersonal and communication skills are essential.
