Issues in getting the negative values of q (mean deviatoric stress) while simulating cyclic triaxial test in ABAQUS using SANISAND subroutine.
Hello Everyone, I have been trying to simulate the cyclic triaxial test using the SANISAND04 subroutine. When I plotting the stress path (p-q plot), I am getting only the positive […] -
How can I solve the error in Abaqus mentioned below?
I am using SANISAND to simulate a triaxial compression test under monotonic loading. But every time my simulations break and give the same message “Abaqus/Implicit Packager exited with an error […] -
consistent tangent stiffness calculation in hypoplasticity sand UMAT
Dear all, Thanks for hypoplasticity sand UMAT provided by Prof. Masin. During studying hypo sand UMAT, I am encountered with a question about consistent tangent stiffness calculation. subroutine ”perturbate_h“ seems […] -
Hypo-sand UMAT problem
Dear community I have 4 Question in implementation of Hypo-sand Umat in ABAQUS could someone kindly explain? 1. I checked the Umat file from (https://soilmodels.com/download/plaxis-umat-hypoplas-zip/) and i understand this subroutine […] -
Compatibility of subroutines in ABQ2021
Hi Admin, I have been using hypoplastic subroutine supplied by this website. It works well in ABQ6.14 and ABQ2017. However, recently I have to upgrade to ABQ2021 due to an […]
