The Diamond Anvil Cell is used in ultra high pressures experiments. It allows us to create conditions of pressures of several millions of atmospheres and to study the physical properties of a sample under these conditions. Although often considered as a rigid body, diamonds undergo very large elastic deformations near the sample region. As a student, I used Finite Element Modeling to calculate such deformations (Merkel et al, Appl. Phys. Lett., 74, 656-658, 1999, doi: 10.1063/1.123031). These are a few model results.
