Structural Integrity

 Materials computational modelling, stress analysis, inspection techniques, advanced metallurgical investigations and experimental validation

Structural Integrity (SI) assessment involves a number of disciplines that exist mainly in Aeronautics, Materials, Mechanical Engineering departments and the Composites Centre at Imperial College. It is concerned with determining the performance, durability and safety of equipment that is subjected to a range of operating conditions during use.

The principal disciplines involved are materials computational modelling, stress analysis, inspection techniques, advanced metallurgical investigations and experimental validation. Structural integrity assessment therefore requires several disciplines to obtain reliable predictions.

Imperial College London has been at the forefront of structural integrity assessment for many years. The Department of Mechanical Engineering, in particular, was instrumental in developing elastic, plastic and creep fracture mechanics concepts for predicting failure in components under a wide range of operating conditions. Many of the procedures developed have been incorporated into national and international standards and industrial codes of practice.

SI at Imperial is now expanded to bring together groups of expert within Imperial College who have common interest in the field. It allows optimisation of human resources and equipment at Imperial. The group is a virtual collaborative grouping with good links to industry and research bodies. An interdisciplinary approach able to respond to a wide range of research opportunities is taken within the SI group.
