Triaxial test of cylindrical specimens

Asked by bean on 2020-08-26

Hi all,

I want to simulate a series of triaxial tests of cylindrical specimen, but i didnt find any proper engines,TriaxialStressController seems to not work for my situation, is there any method to simulate a cylindrical boundary?

thanks,

Hello,
one option is the "discretize" the cylindrical surface e.g. with boxes and apply forces the the boxes.
This can simulate confining pressure on cylindrical-shaped specimen.
