I looked at the STATUS plot and I saw that it is still 1 for every Element, even if the MAtrix Damage is 1. How can I change the STATUS of the Element to 0 so it fails?
Here are my Metrial Properties for the definition of the Composite Plate. As i said I use mm, MPa, tonnes, seconds etc.

Now I got this Error message:
"Excessive incremental rotation of the elements in element set ErrElemExcessIncrementalRotation-Step1.
There is only one element with excessive rotations"
I also get this in message files:
"The ratio of deformation speed in element CFK_45-2.1050 vs. the...
For the Plies I use Continuum Shells: https://files.engineering.com/getfile.aspx?folder=c919aa78-2ec4-4b36-b024-6aa29eb0bc22&file=Ply.PNG
Yes Element Deletion is set to "yes"
I have the units right, it still looks like this: https://files.engineering.com/getfile.aspx?folder=d2de3634-bb7b-40a0-bf94-390924a446e8&file=Bohrer_Error.PNG
Has someone some ideas?
Maybe I did something wrong with the units. I use mm for lenght, kg for mass and MPa. What unit do I have to use for the Fracture Energies? I used kj/m^2. Is this wrong? If yes what would be the correct unit?
I checked the output variable for the hashin damage and it looks like this: https://files.engineering.com/getfile.aspx?folder=089fa27d-af04-4025-9bfa-5b449f8e5d07&file=HAshinDmg.PNG
The other Hashin criteria modes look the same.
It is weird because the red parts should fail and thus should be...
I plotted the DAMAGEFT and this is the result: https://files.engineering.com/getfile.aspx?folder=8811b35a-3f50-47b3-b040-72408da563f8&file=result.PNG
I can assume that the damage criterion wasnt fullfilled. Am I right? How do I fix this? How can I let the simulation keep going without getting...
I did select STATUS in the field output: https://files.engineering.com/getfile.aspx?folder=b0148e1a-b890-40c9-9f63-b73df5b6c032&file=Field_output.PNG
And I can see it in results: https://files.engineering.com/getfile.aspx?folder=e0bfd8e3-8bbf-4259-a698-b8709ca5e4c1&file=Output.PNG
It looks like...
Hello,
Im modelling a Drilling operation in Abaqus for a composite Material. I used the following Materialparameters to define the composite: https://files.engineering.com/getfile.aspx?folder=d82992eb-392a-4c99-8ffb-421b9abb41c9&file=Hashin.PNG
I used Hashin Criteria for Damage modelling. But...
I only got these values: https://files.engineering.com/getfile.aspx?folder=81c1f80d-dbe1-4e62-8f0c-55c2aa0a258c&file=Values.PNG
Can i somehow Calculate the Exponent? Or can I not use mixed mode Behaviuor? Then I only need the Fracture Energy...
Thank you. It works, you really helped me. May I asked one more question? Do you know what I can take for the "Power Law Exponent" or "BK exponent" in the mixed mode Behaviour, when i define the Damage Evolution for the cohesive? I cant find any value for my specific Material. I have no option...
Thanks for the answer. I tried it with General Contact, but then i get this issue:

Hi,
I am currently using Abaqus Explicit to model a Drilling operation for a composite. I want to evaluate the delamination that occurs during this process.
I modelled the Cohesive Behaviour with cohesive surfaces and use the interaction menue to connect the two plies. I used Surface tu Surface...
