Background

Dr Xu received BEng and MEng degrees in Mechanical Engineering from Zhejiang University of Technology, China. He obtained his PhD from the University of Southampton working on damage tolerance characterisation of high strength airframe aluminium alloys. 

Prior to his current appointment as Senior Lecturer in Structures and Course Director of MSc in Advanced Lightweight and Composite Structures at Cranfield University, Dr Xu was Senior Lecturer in Aerospace Structures at the University of Hertfordshire and Fatigue and Damage Tolerance Design Engineer at Airbus UK. He was also a visiting scholar and post-doctoral research assistant at the University of Oxford and had nine years teaching experience at the Zhejiang Sci-Tech University, China. He is the Fellow of Higher Education Academy (FHEA), Member of the Royal Aeronautical Society (MRAeS) UK, and the member of the International Scientific Committee of the International Conference of Fracture and Damage Mechanics. 

Dr Xu has over 30 years teaching and research experience on structural integrity of lightweight materials and structures and developed an in-house structural integrity method (SIM1014) for Airbus. He has carried out following funded projects:
  • Development of a novel, affordable neonate/infant transport incubator, funded by Innovate UK/mOm Incubators, 2017 - 2019;
