damage criterion or cohesive element

[Mari88]

Hi to everyone!
I'm trying to simulate impact damage on composite materials using also cohesive elements... but I'm trying to do this with solid elements because with shells I don't understand what kind of interactions I need to use (between a single shell that simulates a ply and the cohesive, cause they are distant so there isn't a real contact in the model) ... so I have not a damage criterion (for the lamina part) implemented in Abaqus itself (cause Hashin criterion is only for shell parts)...

Is there anyone that has already done a subroutine with a damage criterion for solid elements?? Could you give me an example, please?? I'm very desperate...

Even if there is anyone that can help me with the interactions mentioned above.... please!!!!

Thank you to all could help me!!!

Sounds like a full-scale research project. A few drawings would be helpful (please don't place them on ENGINEERING.com though; a URL of a web page would be OK).

Hi!
Thank you for your reply!
The model is very simple: the ply is a 100x50x0.15 mm plate (solid element or shell, these are the dimensions) while the cohesive is a 100x50x0.0045 mm plate, the 'impactator' is a 7mm diameter ball.

What kind of drawings do you need (in order to give you the right one)?

Thanks!
