This unique course has been designed and developed to meet the needs of design and maintenance engineers in designing, analysing and maintaining aircraft. Read more Read less

It presents the basic fundamentals of fatigue and fracture mechanics, as well as practical methods and case studies for meeting the durability and damage tolerance requirements.

The course consists of two main parts. Part 1 presents the basic theories of fatigue analysis and fracture mechanics, which is also suitable to automotive and civil engineers. Part 2 is designed to enhance the learning objectives offering specialist topics and case studies and exploring in greater depth. The course is focused largely on metallic aircraft structures rather than polymer composite aircraft.  A separate course on polymer composite aircraft structures is available - see "Design, Durability and Integrity of Composite Aircraft Structures".

Speakers

As well as benefiting from the expertise of a number of Cranfield academics who are experts in their field, you will also benefit from the expertise of invited external speakers.

  • Professor Phil Irving, CAA Chair in Damage Tolerance at Cranfield University and Head of the Damage Tolerance Group. Phil has been teaching, researching and publishing in the field of fatigue, structural integrity and damage tolerance in both industry and academia in metals and in polymer composites for the past 30 years.
  • Professor John Bristow, Visiting Professor of Structural Integrity to Cranfield University; Co-founder of Airworthiness MSc programme. Formerly Head of the Structures and Materials Department of the Civil Aviation Authority (CAA). John has over 40 years of experience in the aircraft industry, in structural design and regulations, the De Havilland Division of H.S.A, and subsequently worked as a structural design surveyor covering both structural design and continued airworthiness aspects of all types of aircraft, metallic and composite, for the CAA.
  • Dr Wenli Liu, Key lecturer in the Aerospace Vehicle Design group of the Centre of Aeronautics at Cranfield University, leading research and teaching in F&DT of Aircraft Structures both for metal and composites. Wenli has gained broad knowledge and experience in aircraft design and structural analysis with the aircraft industry over the past 20 years and supported A400M and A350 wing design and analysis for Airbus and GKN.
  • Dr Alain Santgerma, Joined the Fatigue & Damage Tolerance department in Airbus in 1994 with a masters degree, and subsequently obtained his PhD from the French National Institute of Applied Sciences in 1997 (subject: Widespread Fatigue Damage). He worked on all life extension projects launched in Airbus, from A300 to A340. He has been involved in US and European Ageing Aircraft Working Groups for 15 years. As a Fatigue & Damage Tolerance expert, he advises on the design, certification and continued airworthiness of most Airbus products on topics such as major tests and analyses. Since 2007, he has been leading a transnational team dealing with stress policies & directives, fatigue spectra, and major test activities for all Airbus products. Today, he is involved in compliance demonstration to the Ageing Aircraft regulations.
