Hi Henrique,

Attached is an Axisymmetric model of the diamond window on a steel shoulder subject to 1 GP of pressure on the top and side, using linear materials.

The compressive stress is around 7.7 GPa. Some of the stronger grades of steel have tensile strengths up in this range, but many are lower so you will have to select the steel carefully.


The tensile stress in the window is about 3 GP.  You didn’t say what the ultimate tensile strength of diamond was.
