Whether polyhedral particles are suitable for triaxial tests？

Asked by William

Hi, everyone.
Irregular particles are often used in triaxial tests and spherical particles cannot meet our needs usually. The irregular shape particles are realized by clump method in Yade. However, whether polyhedral particles are suitable for triaxial tests？How computationally efficient is it and can we extract contact information or other important information from this method?
Thanks.

Hello,

> whether polyhedral particles are suitable for triaxial tests？

yes

> How computationally efficient is it

obviously it is more "expensive" than spheres.
How much, depends on used contact law, actual shape used (polyhedron, potential block, ...) and other factors.

> can we extract contact information or other important information from this method?

yes

Cheers
