Problem relating to Contact Pressure in ABAQUS Subroutine

I have already obtained the contact pressure (CPRESS) in the ABAQUS model.

NOW, I want to introduce a subroutine in ABAQUS which enables setting the contact pressure as input information, since contact pressue is the intial condition for another model which will incorporate with the existing model. I wonder if anyone can provide some suggestions on which subroutine can read the CPRESS (CSTRESS) as input information.

Many thanks!

The only subroutine that reads in contact pressure is obvioulsy FRIC. So, try to define a FRIC routine; possibly a dummy routine only or you need to rewrite the prevailing friction law as a FRIC routine. Within FRIC, CPRESS equals p (I assume these quantities are equal or define some equation), and finally assign these values to the state variable array STATEV. You do not need to define a variable CPRESS within FRIC, it should suffice to put STATEV(1) = p, I assume. Statev is a global array and available in most routines.

Caution: statev space needs to be defined with DEPVAR.

I do not know how to enforce a call to FRIC prior to the routine where you want CPRESS be available.

I recommend you become a member of the ABAQUS mailing list

Dear Frank,

Thanks a lot for your reply. I will try your method. Btw, I have already sent a request to the mailing list that you recommend. Hope to have more communication with you on this problem in the future.

Best regards,

Yi
