We are the Rock Mechanics lab at TU Delft. We will post about the rocks we break and the resulting science. By Anne Pluymakers and Auke Barnhoorn

Going home. Thanks for all the inspiring science @epostcsah.bsky.social and @rocklabstrasbourg.bsky.social 🤓 #breaking rocks #rocks!

On my way to Strasbourg, to visit @rocklabstrasbourg.bsky.social and to connect with the @epostcsah.bsky.social community. I got to admit, traveling per train beats the plane by a mile! Better views, better seats, better WiFi. Now if there wouldn't be any strikes on the way... It would be perfect

Excited to be back at PSI with the crew from Njord to shoot with neutrons and X-rays at rocks to investigate flow and precipitation in basalts

Anne Pluymakers got a #Vidi grant from Dutch #NWO to investigate why different fluids make limestone break in a different way, and to see if we improve our acoustic and electromagnetic monitoring for #geothermal energy and #ccs... And so our team grows (a bit) 😁🤓 www.tudelft.nl/en/2025/citg...

No less than five researchers from our faculty will receive a Vidi grant this year. The Dutch Research Council NWO awards the grants to successful scientists to give them a helping hand in further dev...

*Krak!* In case you think salt always flows.....in Jops PhD project it is all about breaking salt. And it does so quite nicely, if you push it enough!

Shihao is on a roll! Last week he presented in Beijing, today in Cyprus... And in between he submitted the final draft of his PhD thesis to the Graduate School! 😎🤓😁😁😁

PhD candidate Jop is crushing it! Trying out how mechanically homogeneous and repeatable the homemade salt rocks are 😁

Sometimes you mechano-chemically torture rocks and not much happens... But still good to know! Check out our new publication to see that 6 months exposure to H2 did not change the mechanics of these sandstones... www.nature.com/articles/s41...
Hydrogen solution exposure at a seasonal timescale does not affect the geomechanical properties of clay-rich sandstones

Disco-salt! This is a very salty day, meeting with PhD Jop on his salt project but also sitting in a national salt meeting talking about what's happening in salt. This salt block is standing in our lab post-lab-torture 😁 happy Friday all!

It's basalt time! Working on a few samples for Njord Oslo, who invited Anne to join their trip to PSI in November to shoot neutrons at rocks again

Team Salt on the move! Brazilian disc testing with camera plus acoustics on healed samples fractured last spring 🤓😁

Former PD Debanjan Chandra is visiting from Norway to run experiments with an #EPOS-NL grant and he is explaining his new experiments whilst monitoring his stuff. Multi-tasking at its finest!

A first attempt at cold pressing our own salt samples, which will be baked afterwards for Jops PhD project. If anyone has any tips, we gladly take them!
