I would be grateful if you could give me any advice or maybe suggest some literature. Thanks in advance.
The Düsseldorf Advanced Material Simulation Kit (damask.mpie.de) was developed with exactly this question in mind. One can use it for direct and statistical crystal plasticity, i.e., finite elements smaller or larger than a grain, and introduce arbitrary constitutive laws, such as the one of Dr Liu as mentioned by Hojjat Badnava.
Adding your own constitutive law (instead of using existing ones being distributed with DAMASK) is quite straightforward, since only a few clearly defined interface functions have to be respected. It typically involves copying the Fortran module source code of an existing constitutive law and adapting that to reflect your constitutive description.
I would be interested to work with you on this. As one tangible outcome, I could foresee a guideline/tutorial on the DAMASK webpage based on your experience with the above procedure.
Maybe you can use user created material UMAT. Here's an example on single crystal plasticity :

I believe that the DAMASK package is also an option.

Dear Dr. Alexandru, Mr. Manninen, and Mr. Badnava, thank you very much!

I wish to be in this discussion page for developing knowledge in Crystal Plasticity.
Dear Olga Zinovieva,
I think you have received good responses
I just add two links, maye be they can help you.
http://www.dierk-raabe.com/polycrystal-mechanics/
https://icme.hpc.msstate.edu/mediawiki/index.php/Code:_ABAQUS_CPFEM
If you are beginer, I addvice you to review Cristal plasticity theory at first
after you can follow samples in youtube on how you can prepar the UMAT subroutine and implement it in ABAQUS
Good luck and Greetings
Mourad
cohesive (U can find all dettails in Neper polycristal) or use algorithme using materiel science approach, U can find them in
https://damask.mpie.de/Home/WebHome
or
https://icme.hpc.msstate.edu/mediawiki/index.php/Code:_ABAQUS_CPFEM
U wil find many doc in these links.
or just tape CPFEM

Dear Philip Eisenlohr ,
I have installed the DAMASK successfully with the help of the Internet. However, there is no specific tutorials about how to carry out a simulation. I have read all the Documentation from the website(https://damask.mpie.de/), but still do not know the complete and specific analysis procedures. If there is any step-by-step simulation tutorials, that will help me a lot. Thanks a lot !
Hi Mourad Dougdag ,
Thanks for your good advice.
I have a question. How to import the files generated by Neper into Abaqus for CPFEM?
Dear Zhengwei Fan,
In Neper, you can choose the "*.inp" output file. This type file is read by Abaqus.
Good luck.
Mourad
Hi can anyone share any tutorials/videos on how to do crystal plasticity using DAMASK and Abaqus software? i am very new to DAMASK software. i Have created a 3D model of titanium microstructure with dual phase composition using Neper software. I am planning to do quasi static damage model using damask. tq
Dear J.T. Karthigesu Thanarasi
May it could help:

Good luck.
hi all,
Is there any other way to introduce Crystal Plasticity using Abaqus other than using DAMASK. ? I have been running into many problems using DAMASK WITH ABAQUS. Please advise. i would like to do CP analysis for HCP crystal and the micro structure i designed using neper. Thank you guys.
Xin Wang how to do the section assignment and material during creating the inp file in Neper?
thanks.
J.T. Karthigesu Thanarasi
You can do section assignment either in ASSEMBLY or PARTS.
KEYWORDS:
*SOLID SECTION, ELSET={elesetname}, MATERIAL=MAT{material identifier}
you can add some section controls command below this line
After you creating the sections, you need to define materials properties for each sections:
KEYWORDS:
*MATERIAL, NAME=MAT{material identifier}
I wrote some codes to automatically write these information into INP file based on the UMAT from Prof. Huang, Yonggang, hope it helps:
