Your feeling of 10% reduction is valid, because a lot of the time "feel" from someone experienced is valuable, which is what that sounds like.
Do you have the ability to run a simulation for me to verify?

You asked this question twice so you must be curious.
The void is actually a low hardness material, Shore 40A potting material. Comparatively it is negligible in compression strength. The sphere material is a thermoset that is molded and cured around the inner part for a specialized...
No. Cube length is 75% diameter of sphere. It will fit inside.
What I want is something like this: eliminate corners as suggested. Here is a quick simulation I made using a cylinder void instead of a cube void, with a static compression test, and visually it shows that the stress distribution...
I want to know by how much the external compression strength is weakened by introducing a cubic void into the center of a sphere.
I am an electrical engineer with a basic but not fully functional understanding of continuum mechanics, and I figured one of you guys could probably run a few quick...
