Probabilistic Engineering Critical Assessment Webinar Held

Tue, 05 January, 2021

TWI recently held a webinar on engineering critical assessment, which addressed several initiatives currently underway at TWI and NSIRC.

The event, titled, 'Engineering Critical Assessment: From Qualitative to Quantitative,’ took place on 3 November 2020 and saw almost 600 people register and over 300 attending on the day.

Professor Isabel Hadley, Technology Fellow at TWI’s Materials and Structural Integrity Technology Group, highlighted a number of current projects in her presentation, including:

  • TWI Core Research Programme (CRP): A comparison between ‘top down’ (risk-based inspection/RBI) and ‘bottom-up’ (probabilistic fracture mechanics/PFM) approaches to reliability of pressure vessels and pressure piping, and the implications for codes and standards
  • National Structural Integrity Research Centre (NSIRC): Probabilistic treatment of welding residual stress, and how this can be incorporated into PFM calculations
  • Industry-driven programmes
  • Progress towards incorporating probabilistic fracture mechanics into codes and standards

We would like to thank Professor Hadley for her presentation and Matthew Haslett for his contribution in the Q&A session which followed, as well as thanking all of those who took the time to attend the virtual event.

The recording of the event is now available to watch here.
