The webinar is designed to introduce attendees to the theory behind the application of fracture mechanics (FM) principles for the analysis of fatigue cracks in bridge details. This will be discussed within the context of bridge management decision-making.

Areas that will be covered will include:

  1. Introduction to the process of fatigue (crack initiation and crack propagation behaviour)
  2. Introduction to fracture mechanics (Linear Elastic FM, stress magnification factors, fracture toughness)
  3. Introduction to fatigue analysis of cracks (Paris law, typical values for FM parameters, prediction of fatigue life)
  4. Fracture mechanics and bridge management (Example of the application of fracture mechanics for maintenance planning)

Presenters

Dr Boulent Imam is a Senior Lecturer in Civil Engineering Structures at the Department of Civil and Environmental Engineering in the University of Surrey (England) and Programme Director for the MSc Programme in Bridge Engineering. He has been extensively involved in the area of fatigue of bridges, carrying out research in this area collaborating with national and European infrastructure owners and managers, such as Network Rail, Highways England, TWI. His research has contributed towards in-depth understanding of the fatigue behaviour of riveted railway bridges and developed methods for more reliable quantification of their remaining fatigue life taking into account historical rail traffic, novel fatigue assessment methods, loading, resistance and modelling uncertainties as well as system effects. Later on, Dr imam extended his work on fatigue towards developing fracture mechanics guidelines for the assessment of fatigue crack growth in steel bridge details towards the optimisation of inspection and maintenance planning in steel bridges. Recently, Dr Imam research has expanded towards understanding the potential impacts of climate change on bridge deterioration and quantifying the resilience of bridge infrastructure against extreme events.

Format

There will be opportunity to interact with the lecturer throughout the session, both though allocated Q&A sessions, or leaving text based questions throughout the presentation which the lecturer will be able to answer at convenient opportunities.The format of this event will be a webinar using "Zoom Webinars".
