Aalto University has had the pleasure to host a public lecture of Professor Dragan Grgic (GeoRessources Laboratory, Université de Lorraine). Professor Grgic visited Finland due to cooperation with VTT and GTK. During the visit, he kindly agreed to held a lecture at Aalto.
Professor Grgic presentation can be downloaded here.
We have attended the 2019 MPM conference in Cambridge in numbers. I had a presentation on Uintah software and a keynote, while other members of the research group presented their research. You can find the proceedings here: http://mpm2019.eu/papers
In particular there are some presentations available:
And the conference papers:
On the way back, I have been given opportunity to present my research at Imperial College London. In particular, you can download the abridged presentation related to our research with Dr Abed in project THEBES: THMC Behaviour of the Swelling Clay Barriers
Quoc Anh Tran, doctoral student working in the Academy of Finland project on landslide modelling, managed to get a journal paper published in Computers & Geotechnics. The paper shows number of improvements in landslides modelling with the Material Point Method. Those include strain rate dependent, structure dependent Mohr-Coulomb model for undrained analysis. We also used a simple non-local formulation for the shear-band thickness (Pinyol et al. 2017), which reduces mesh dependence. After validation, the paper shows some – I dare to say – rather nice simulation of a Saint-Monique landslide.
The paper is open access, download it from here:

Enjoy!
Last several months have been really busy, with me having really no time to catch my breath (but well, we have now 5 journal papers under review, keep fingers crossed). Recently, SeyedMohammadJavad Seyedan presented in the beautiful city of Porto in the NUMGE 2018 conference. He was explaining how to enrich the constitutive model for soil with capability to model the small strain shear nonlinearity. It is a neat expansion, which has also thermodynamical consistency (note: full paper under review)… Then, Dr Ayman Abed presented on chemical coupling (download paper) in UNSAT Conference in Hong Kong. That is a nice effort with cooperation from UPC BarcelonaTech. Finally, I have been presenting in Vienna Dr Yang Xiujuan paper on water retention behaviour of MX-80 bentonite, when partially saturated with saline solution, as unfortunately Xiujuan could not come to Vienna.

Hey,
Today in the beautiful city of Milan, I had a seminar at the Politecnico di Milano on the bentonite behaviour modelling, related to THEBES project. The slides are here. Also, the keynote lecture in the IV ECCOMAS YOUNG INVESTIGATOR CONFERENCE – YIC2017 entitled “MPM or FEM / PFEM / SPH /… Insights on the Material Point Method future” is here. In case you need more information or the movies (sorry, no movies in the .pdf), please do not hesitate to contact me! We are always happy to share!
Enjoy!
is now on-line!
For the paper please follow https://authors.elsevier.com/a/1VXgy,63b~gd8H to get the free copy (link valid until 30th of September). Afterwards, please contact me for the copy if you need one… The paper is summing up the developments of the coupled Finite Element code for the THEBES project at Aalto.
Dr Núria Pinyol, Associate Research Professor at UPC BarcelonaTech is currently a visitor at Aalto, thanks to the support of UPC and the EU Erasmus+Teaching Mobility Grant. It is my great pleasure that in the beginning of September, we are holding an Intensive course on Geomechanics of Failures together at Aalto. Everyone is welcome!
You can register for the course in the Aalto system. In case you are from outside, please let me know at my Aalto University email and I will register you so you can attend the course.
The course will cover three important case studies:
Mexico City Metropolitan Cathedral – case study related to settlements calculations and interaction between neighbouring structures
Vajont landslide – case study related to the behaviour of large landslides and slope stability calculations
Barcelona port caisson failure – case study related to the pore pressure build-up due to cyclic loading in undrained conditions.
The lectures are related to Geomechanics of failures by Puzrin et al. 2009 (chapters 1 & 5) and Geomechanics of failures: advanced topics by Alonso et al. 2010 (chapters 2 & 5).
The course page is currently not very up to date, but more information will be given here.
We have recently been in Trondheim, the truly charming city with Nidaros cathedral, famous for its organs. The reason was the Workshop, where Quoc Anh Tran had a very nice presentation on MPM simulation of sensitivity test.
The research has been very well received. The paper has been published here. Please contact me or Quoc Anh if you have problems accessing the paper…
Thanks!
This site is independent from the Aalto University organisation and as such all the materials here are not necessarily supporting Aalto University views and policies. Even though the majority of the posts here are strictly related to my work and as such may link to the Aalto resources, the site may also provide my own opinion and views – those are my own views and not necessarily the Aalto University views. The posts here are also not pre-approved by the Aalto University communication team.
The other reason why the site is made separately from Aalto University is due to the lack of stability in the Aalto ecosystem. Many of the research pages I created when I came to Aalto have been deleted due to the department restructuring and merging. Unfortunately, I have not been given space to migrate them within the new Civil Engineering Department website. It seems that the best way to avoid such an experience in the future is to have a site which is not connected to the Aalto infrastructure and outside of the Aalto decision making system.
