Hi all.

 

What is the pressure the ice would exert to a rigid hermetic strong enough container if fully filled with water and exposed to freezing ?

A LOT!

 

Assuming that the water freezes solid into normal ice at 32F, find the bulk modulus of ice, then calculate the stress knowing that you'd have a strain of about 10%

 

A spoiler to this is that the freeing temperature of water drops as pressure rises. then, under sufficient sufficient pressure, ice can form alternate crystal stuctures that are more dense than normal ice, and that have different melting temperatures.

I tried it several years ago with a section of a .22 Rifle barrel, it still blew the end out, good Luck!

you're going to be looking at around 2 gigapascals. probably a good deal more. shoot for around 20-30GPa and it should be fine.

also, it will not be the same as normal ice. it will not have the same crystal structure.

 

if you want to build a container i would try getting a solid block of high tensile steel and hollowing out the chamber. then would would need to weld the plug shut.

 

on the plus side, there are some ices more dense than water but the tend to be at extremely cold temps and high pressures so unless you have a bunch of liquid nitrogen around you won't get them.
