Thank you very much for the explanation.
Can you make a video to include the damage in UMAT

[@Professor3MEC]

Yes, soon

[@ahmedaljumele2701]

@Professor3MEC Thank you very much. That will be awesome

[@zulfiqarhussain3645]

Thank you for making this video. I am facing problem in implementation, the subroutine has no issue during compilation. But the Abaqus abort with error "ErrElemZeroHourGlassStiffness". I am using the same model for UMAT as used for Abaqus default material by changing it to user material. Also, the strain crements are zero. Appriciate your assistance.

[@Professor3MEC]

There could be various reasons.
- check if all the material properties are being defined and read by subroutine correctly
- print out stiffness matrix and see if all is correct
- check if an element type used needs enhanced hourglass in the mesh module
- etc

Part 7 is messing

[@Professor3MEC]

it should be there.
