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.
This little picture may not seem like much. But it's huge! This was our first ever attempt at imposing a sinusoidal load on top of a background load, at various frequencies (white curve). A new set up was used such that a stationary base was beneath sample (so that it can't slide). The resulting purple curve was the displacement of the sample. In this case we just used teflon, but it shows that all the components for controlling and measuring low amplitude cyclic loads are there. I'm very very excited about this.
