When a thin elastic disk is pushed into a hollow cylinder by an indenter, the so-called d-cone [1] is observed. It has been shown that close to threshold, the d-cone solution coexist with regular buckling of the disk [2]. Using a similar experimental set-up, we extend this static study to take into account the influence of gravity on the state diagram of the system, and show that new branches of solution appears. We also look at the dynamics of (dis)appearance of the d-cone from the buckling branch.
