Over the five days we had attendees representing academia, research centres, start-up companies, and large multinational corporations joining us. Once again, the training course (Day 1-2) was oversubscribed. The forum (Day 3-4) was well-attended by a mix of new and returning attendees. For the third time, the event was hosted by the IOP at their headquarters in London.
Keynote Speakers
Prof Jean-Charles Passieux, INSA Toulouse, France
Generation of analysis suitable B-Spline beam models from digital images
JC Passieux is a full professor of Computational Mechanics at INSA Toulouse, France. He develops high-performance computational methods (domain decomposition, reduced order models, local/global coupling, Isogeometric Analysis). He has contributed to the development of finite element-based and global digital image correlation (DIC) methods, identification from digital images, image-based models and data assimilation. He was co-chairman of the international conference Photomechanics 2018 in Toulouse. He is a member of the steering committee of the Computational Solid Mechanics Association (CSMA, France). He is one of the founding members of the French PhotoMechanics Association.
Dr Fabrice Pierron, Matchid NV, Belgium
Integrating 2D/3D images with numerical simulations for mechanical deformation analysis
Dr Fabrice Pierron has been a Professor of Solid Mechanics at the University of Southampton since 2012. He is a specialist in the integration of image-based deformation mapping (like digital image correlation) with inverse identification (like the Virtual Fields Method) to design the next generation of mechanical tests. He has published more than 150 journal articles. He was Editor-in-Chief of the journal Strain (Wiley) for ten years and is a co-founder of the company MatchID NV (Ghent, Belgium), for which he now also works as R&D Director since 2021. Prof. Pierron is a Fellow of the Society for Experimental Mechanics (SEM).

Fri Oct 2023
An entire day dedicated to exploring opportunities for collaboration. This may be to build teams for writing funding proposals, solving particular challenges, round-robin testing, seeking expertise to complement an existing research team, or other activities of a similar nature.
Since its inception, a primary aim of the IBSim-4i event series has been to foster networking and building of working relationships, particularly between industry and academia. This dedicated collaboration workshop is standalone from the rest of the IBSim-4i week, and interested parties may attend for this day alone if desired. We particularly encourage those planning to attend to invite other potential stakeholders and look forward to exploring R&D opportunities with you and your colleagues.
Themes for 2023:
- Working with large datasets (TBs), e.g., those generated at synchrotrons
- Composite materials
- Material Testing 2.0: the next generation of material test based on deformation imaging
- IBSim benchmarks preparing for ‘Digital Twins’
- 9:30 – Session 1
Personal introductions– 3-4 minute intro presentations (strict timing, pdf pre-submitted)
* Your research interests & expertise
* Research team & facilities available to you
* Particular topics you would like to be involved in
- 10:45 – Coffee
- 11:15 – Session 2
Theme introductions & Identifying research challenges– Pre-appointed theme leaders to give 10-15 minute overview
– Round-robin post-it session leaving project ideas / research challenges on whiteboards
- 12:30 – Lunch
- 13:30 – Session 3
Research prioritisation– People are free to choose which theme to be stationed at
– Groups discuss which post-it ideas to focus on
– Theme leads report back to the room
- 14:45 – Coffee
- 15:15 – Session 4
Cementing actions– People can either stay at the same theme or move after hearing the prioritised ideas (they could let more than one theme know that they’re interested to be involved)
– Formulate teams to collaborate after the event, e.g., write proposals, (sub-teams within themes might be needed)
– Discuss action plans for follow-up
– Report back to the room
- 16:30 – Close
