EngD Studentship - Application of Advanced Wire Plus Arc Additive Manufacture Technology (WAAM) in Renewable Energy Marine Structures

Renewable Energy Marine Structures

Additive deposition is a unique digital, tool less, manufacturing tool which is capable of building complex components with added features such as improved functionality through creation of composite and multi-material structures. This digital tool less manufacturing technique is in strong focus due to its capability of producing complex engineering components and structures with added features with much simpler logistics, high material productivity and improved recyclability. Welding Engineering and Laser Processing (WELP) centre of Cranfield University is a pioneer in the Wire plus Arc Additive Manufacture (WAAM) and leading the research activities globally in this area. This ambitious and challenging project would critically impact and shape the future of manufacturing in the renewable energy sector. The student will be a part of an engineering doctorate cohort for four years which spans between Cranfield and Oxford University.

In the research, he/she will be mainly focussed on the design principles of structural materials that are currently being used for offshore structures and then exploit the capabilities of additive manufacturing technology to develop components with designed functionalities to reduce weight, increase structural efficiency and reduce overall life cycle cost of a component. Development of multi-material, damage tolerant component, as a proof of concept, would be created and damage initiation (by different service conditions) and propagation characterised to understand its suitability for an intended application in the offshore renewable energy area. 

During the doctoral thesis work, the student will be based in the Welding Engineering and Laser Processing Centre and be a part of a very vibrant PhD research student group working with different aspects in the area of additive manufacture using different structural alloys, metal and ceramic powder, other structural materials and state-of-the-art power sources which is based on welding arc, laser and often a combination of the two mutually complimentary power sources based processes.

The candidate should have an engineering background with understanding on materials response and damage of structural alloys when subjected to dynamic service conditions

On successful completion, the student will receive an Engineering Doctorate degree project within the Renewable Energy Marine Structures (REMS) Centre for Doctoral training (CDT) programme. REMS (Renewable Energy Marine Structures) is an EPSRC funded Centre for Doctoral Training set up to train fifty Engineering Doctorate and PhD students over an eight-year period. Ten new students will be admitted each year for five years starting from October 2014. The new students in October 2017 will be the fourth cohort in this programme. This is a collaborative partnership between Cranfield University and the University of Oxford. The REMS CDT conducts research across the full spectrum of Offshore & Marine Renewable Energy structures integrating deep specialist areas such as geotechnical engineering, the soil-structure interface, whole-system structural design & optimisation, design for manufacture, inspection maintenance & repair and structural integrity including fatigue & fracture mechanics in the marine environment.
