Demonstrate creation of Shear band in triaxial test

Asked by Seti

Hi all,

I need to simulate/show step by step the process of creation the shear band/ cracks during the triaxial test. Can you please help me how I can do it?

Thanks ,
Seti

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
