How Do You Calculate the Minimal Distance Between Two Holes in a Metal Block?

[wispy987]

Hello... first of all, this is my first entry, couldn't find anything similar with the search function...
so here is my problem..

Out of personal interest, i want to know if there is a formula to calculate the stress on a block of metal with two holes. One of these holes will be used for high pressurized liquids (hydraulics) while the other whole will not...
the question is how to calculate the minimal distance between these two holes? Anyone here that has a formula or may be a paper on that subject at hand!

Thanks a lot!

One simple way to do this would be to treat it as a pipe wall thickness calculation. The calculated wall thickness (plus the diameter of the hole) would be the distance between the two holes.

You could use formulas in ASME B31.1 Power Piping or ASME B31.3 Process piping. Many engineering handbooks also have these.
