Hi all, I want to do degradation (perturbation) of subplastic clay with ABAQUS, but I can’t do it with umat, changing K,A,sf in ABAQUS has no effect on the result, do I have to enter 29 parameters in ABAQUS? Do I have to use the subroutine sdvini? What should I do? Thanks for your help.

SImulation with hypoplastic model for granular materials in ABAQUS
Hello, I want to use the hypoplastic model for granular materials downloaded from https://soilmodels.com/download/plaxis-umat-hypoplas-zip. The UMAT file umat.for is the model for sand. I followed the instruction https://web.natur.cuni.cz/uhigug/masin/plaxumat/node5.html. I have […] -
