Robert Caulk proposed the following answer:
Hello,

The shear band develops due to the flexible membrane used in
experimental triaxial compression tests. TriaxialStressController() uses
rigid walls to apply the confining pressures, so shear bands are not
likely to develop.

This thread might be of some use to you [1]. You will want to implement
some kind of flexible boundary. I've seen papers use many small stacked
rigid walls to simulate flexible membranes. I think PFC might use an
external layer of particles to simulate a flexible membrane?

Best,

Robert
