Re: Maximum height of very cold ice mountain ?

I am trying to figure out maximum height a given diameter base
can support, cooled to liquid nitrogen temperature.

Cannot find strain rate data for ice at very low temperatures and high
pressures, into the TPa range.

Can the 1 : 1 1/2 max stable slope of sand dunes be used ?

Resulting shape parabolic as in ice fields ?

Exponential taper as in scale height of a column ?

Try sci.materials as this is really their sort of question.

Be specific in the text of your question defining frozen
water as the material. Also use decimal numbers instead of
fractions where applicable. If you're using anything other
than reasonably pure (triple distilled or better) water,
be sure to specify that as well. If it is a theoretical
discussion don't be afraid to say so.

Also please define what is exerting the pressure and the
conditions involved. For example, are you freezing the
water to the low temp and then applying pressure or is
there pressure being applied at some rate while the
temperature is being driven down? What absorption
considerations come into play? I've probably missed
a few other parameters that need to be known. Timing,
for example, may come into play.

The devil is usually in the details. I feel certain you'll
get excellent information in sci.materials if you pose the
question with the care it deserves. Otherwise it will just
be another case of GIGO.
