FROZEN SOIL

FROZEN SOIL

(OP)
PLEASE, WHAT IS THE EXPECTED MAXIMUM AXIAL LOAD THAT A FROZEN SAMPLE OF CLAY CAN WITHSTAND?
THANKS

RE: FROZEN SOIL

You'll need to test it to find out.

RE: FROZEN SOIL

Interesting question. If you place a heavy load on ice,measured in pressure, the ice there melts. One example is the pressure under a blade of an ice skate. When is that pressure so low that there is no melting and the skate doesn't side? Now mix in some clay and it becomes more complicated.

RE: FROZEN SOIL

the strength of ice depends on the temperature. Bearing in mind that adfreeze shear is the more reliable strength parameter and also bearing in mind that there's a reason ice skating works. The pressure being applied actually reduces the strength.

RE: FROZEN SOIL

Some real interesting stuff about clays.

They can support some fairly good loadings if stiff or very stiff. This can increase with freezing and can reduce with applied loading and thaw under pressure (a feature of ice called regulation). Depending on the soil particle size and the type of clay particle, they can have supercooled liquid in them at -40C/F.

eBook - Functional Prototyping Using Metal 3D Printing
Functional prototypes are a key step in product development – they give engineers a chance to test new ideas and designs while also revealing how the product will stand up to real-world use. And when it comes to functional prototypes, 3D printing is rewriting the rules of what’s possible. Download Now
