Applications accepted all year round

Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project.

The PhD will be based in the School of Mechanical and Design Engineering  and will be supervised by Dr Antigoni Barouni. 

The work on this project could involve:

  • Experimental investigation of delamination growth
  • Development of a Finite Element (FE) model to simulate and predict the delamination on the bonded coupons
  • Experimental and numerical investigation of different bonding parameters on the performance of the joints

Adhesive bonding is now being increasingly used in all industries, from high technology industries (i.e. aeronautics, aerospace, automotive etc.) to traditional industries (i.e. construction, sports and packaging). The characterisation of the adhesive bonds’ performance and its sensitivity over certain parameters is critical for many engineering materials and components. The development of reliable designs and validated predictive models will result in more efficient and well-designed composite structures and adhesives, which in turn will benefit society in various applications starting from reliable wind turbines that provide a sustainable alternative energy source, which is the focus of this project.

This project aims at understanding the performance of adhesively bonded composites by investigating the sensitivity on bond parameters and the predictive capabilities of Finite Element modelling by means of Cohesive Zone Modelling (CZM), which is widely used to predict cracking process in materials.  The direct application of this study will be on wind turbine blades, where a typical blade consists of several areas of adhesive bonding due to its large size. In addition to the bondlines inherent to blade manufacturing process, adhesive joining is employed in repair procedures as well, which makes the purpose of this study very crucial. Experimental tests as well as numerical studies will be conducted on composite joint specimens in order to investigate parameters such as adhesive thickness and different surface treatment methods. The experimental procedure will include the manufacturing and testing of a variety of adhesively bonded coupons and the measurement of the energy release rate (GCI, GCII) of the bonds, as the main indicators of the delamination happening in the boned area. Additionally, appropriate Finite Element models will be developed in order to simulate the tests and study the sensitivity of the debonding prediction on the Cohesive Zone Modelling (CZM) law inputs. Further investigation of the debonding will be conducted using the novel imaging methods of the Zeiss Centre at the Future Technology Centre of University of Portsmouth.

This highly industry-relevant research will pave the way for industry uptake in the renewables energy sector as well as in aerospace industry. This project aligns with the Future and Emerging Technologies Research Theme of University of Portsmouth, which aims to develop ground-breaking solutions and innovations for the practical applications in wind turbine blades design.
