Dear Colleagues,

Due to the continuing pandemic and the travel restrictions we have decided to move IWBDG2020 again, this time to the end of year 2022. 

  • The new dates for the workshop are 28 November – 1 December 2022.
  • Welcome reception – 28 November 2022.
  • The name of the workshop remains unchanged, IWBDG2020.
  • New Abstract Submission (the submitted abstracts do not have to be resubmitted) – April 15, 2022
  • Notification of acceptance of new abstracts – May 4, 2022
  • Manuscript Submission (the submitted manuscripts do not have to be resubmitted) – June 10, 2022
  • Notification of revisions – June 6, 2022
  • Final Submission – July 31, 2022


The Organising Committee is looking forward to welcoming you at the 12th International Workshop on Bifurcation and Degradation in Geomaterials – IWBDG2020.

After the last highly successful meeting of IWBDG in May 2017 at Limassol, Cyprus, this year’s workshop will take place on the 29th of November to the 2nd of December 2021 in Perth, Australia at the beginning of the Western Australian summer.The organisers hope that the combination of interesting presentations, discussions and a good weather will make the workshop enjoyable and leave a good memory of the event. 

In accordance with the workshop’s objective to promote insight in bifurcation and degradation in geomaterials, scientists are invited to present recent advances in instabilities, localised and diffuse failure, multiscale, multiphysics, micromechanical modeling and other related topics. A major goal is also to promote the link between theoretical and applied mechanics with engineering applications in traditional and in emerging fields, such as geomechanics for the Energy and the Environment. The meeting encourages, in particular, the participation of Young Researchers at the doctoral and post-doctoral levels by applying moderate registration fees.
