VUHARD

Hi all,

I am new at subroutine and abaqus requirements and its compatibility. I am trying to use a subroutine VUHARD for the material modeling of polycrystalline material under shock loading. I am not sure if I can use VUHARD because of my lack of experience in subroutines. I have couple of questions listed below and I would really appreciate if anyone can give me a insight in this subject.

1) Can I use visco-plastic formulation (rate- dependent) in VUHARD?

hello

I works with subroutins in ABAQUS.

I  have written a vuhard subroutin and I have some problems.

who  does work with this subroutin that can help me?

With regards

HI,

Hello

I am working on the simulation of ring rolling. I have written the subroutine for the plasticity part in the subroutine VUHARD and have set the PLASTIC part in material definition to USER.
I dont have HARDENING PROPERTIES so i have set it BLANK. i have set the path of the subroutine in the job defintion part too. But abaqus crashes whenever i try to do DATA CHECK
It says ABAQUS KERNEL EXITED WITH AN ERROR.I dont know why this problem arises?. I am stuck.
