Hello,
I am using the "simple" model you can see on the images below.
I would like to use the FRIC subroutine to define a friction model. I would like to start with the Coulomb model and then define another one more complicated.
But I don't know the Fortran syntax. So it would be very helpful to get some help about how to write a FRIC subroutine and then how to use it in Abaqus.
Thanks a lot.
Hi,
Find the attached subroutine file, with the algorithm of Lagrangian and coloumb friction.
I hope it helps.
Dear Thanwerdas,
Please find the attached document for your help. You may find the syntax and then take help from Abaqus documentation.
With regards,
Abhishek
Hello Abhishek,
thanks for your help. Unfortunately, I already know this document and it does not contain anything helpful on the FRIC subroutine...There is only a definition at the beginning and that is all.
Maybe you know some other documentation ?

Hi,
thanks a lot it is very helpful.
However, when I used the Coulomb subroutine, it seems the PROPS(1), which correspond to the static friction coefficient, is not read in the subroutine. Though I specified it in the CAE.
Do you have any clue ?
How do you know that its not recognized?
Did you check the log file?
You can however define Props(1) as a constant in the subroutine and dont give it in cae. Then you can be sure whether props(1) is the problem or something else !
For e.g.
Xmu = 0.2 instead of Xmu = props(1)
check for errors in parallel studio,
sometimes C is not at the first coloumn, and sometimes the continuation line in not in the 6th coloumn.
Hi,
it is working now ! It was a problem in the version of Visual Studio...
thanks for your help.
I recommend you become a member of the ABAQUS mailing list

Does anyone know what the unit of frictional stress τ？ MPa or N? And what about the relative sliding motion γ ? mm or like strain without unit?
