Dear PhD,
I am studying roller vibrations on sandy soil models with vumat. Can PhD give me the subroutine model and input parameters of objects for reference?
Unit of the subprogram used?
Many thanks.
Hoang An

Dear Hoang, I am not sure whether I understood correctly your question. In any case, vumat implementation for hypoplastic model is here: https://soilmodels.com/download/vumat_umatinterface-zip/. Please study the related references to find example parameter sets. Regards David
Dear David Mašín,
I am a new user of abaqus. Good, Dr. can give me an example of a complete soil model using vumat for hypoplastic model.
Thank you very much, Dr. for example .inp and .for files.
mail: sg-thaihoangan@e-university.edu.vn
Best regards
