😎Excited to share our latest research in Phys. Rev. E! Our paper explores how grain angularity affects cohesion in granular packings.

Geometric cohesion in two-dimensional systems composed of star-shaped particles, David Aponte, Nicolas Estrada, Jonathan Barés, Mathieu Renouf, and Emilien Azéma #GranularMatter https://t.co/IkWCyX42hf

Latest paper: with @dacantor & Carlos Ovalle we show (and explain why) that the currently accepted construction of effective and capillary stress tensors for wet granular assemblies is no longer valid in polydisperse granular material !

In our last published article in the journal Open Geomechanics (https://t.co/c6R6kmWfMX), we studied the effect of particle shape and size correlations on the steady shear strength of granular materials, combining rounded, angular, and irregular grains. Thanks @polymtl and RIME

@c_abrer_a @AzemaEmilien @NEstradaMejia @SantiagoPolana I'd just like to add that -to the best of my knowledge- it was David Muir Wood who first made this observation using DEM.

@c_abrer_a @AzemaEmilien @NEstradaMejia @SantiagoPolana What great work folks! A paper like this was so badly needed. When I’ve presented the numerical results with spheres and octahedra at conferences, this topic is usually received with a lot of skepticism, so it’s very validating to see this out 👏

[David Cantor @dacantor]

🔝 on my list for best paper titles so far this year!
@AzemaEmilien how about some non-convex simulations of something like this? 😎

@vjagodnik These are some of the papers showing what I mentioned in the first tweet.

@vjagodnik If you are interested in peak strength, there is not a lot of DEM out there about that. That's a very broad topic and simulating broad gradations with DEM is very challenging/problematic.

[Chris Johnson @grainsandfluids]

🚨Postdoc available! A three-year @NERCscience funded postdoc on modelling debris flow dynamics will be available at the University of Manchester @UoMSciEng, starting early 2023.

⭐️Please RT and pass on this early announcement to potential candidates. DM/email me for details.

[David Cantor @dacantor]

Bravo to the team that performed these experiments! We worked very hard on the theory of compaction & seeing its experimental validation is very satisfying! I hope civil engineers and physicist will find these works useful for the study/design of natural/next-generation materials

[Azéma Emilien @AzemaEmilien]

Find out our recent paper!We experimentally validate & extend to uniaxial compression the "Cardenas-Cantor" compaction law for soft, soft/rigid 2D grains assemblies far beyond the jammed state.
