The rock and ice mechanics lab at Lamont-Doherty is led by PIs Heather Savage, Christine McCarthy and Ben Holtzman. We are in the process of growing our lab and building our experimental program. Along with a team of postdocs, undergrads, grads, and longtime staff engineer Ted, we are rehabilitating and revamping some of the old equipment and building new rigs for exciting new experiments on both rock and ice. You can follow along with our progress here.
After the dry run was complete, it was time to move on to the real thing: ice-on-rock. Mike made a plexiglass front to the cryostat so we could watch what was happening and still keep things moderately cold (also thanks to our friends burlap and bubble wrap). Here it is in its "double direct shear" starting position...
...and afterward. We successfully slid ice past rock with an applied normal load (~100kPa)
A toast of champagne to celebrate!
And a paper describing the apparatus is found here.
