Anisotropic non-linear material with asymmetric behavior in tension-compression

[Latecoere]

Dear Abaqus users,

1.
I would like to simulate an anisotropic non-linear material, with different behaviors in compression and tension domains.
I have realized tests that provide me different plastic curves in compression and tension, and for different directions.
> Is it possible to specify this in a non linear material property? Could you help me in finding documentation on this subject?
> If it is not possible, I’m rather interested in modeling an isotropic material, but also with a dissymmetric behavior.

2.
I have another question about the use of these data, it concerns crash simulation domain, where I’m not familiar.
I would like to make an explicit analysis to simulate an impact on a plate made of these previous material properties.
> Will my material be compatible?
> What would I miss? Damping data? Structural damping coefficient?

Thank you in advance.
Best Regards,

Cyril

Look at the fabric material in the documentation and check the impact on an airbag example.

Hi IceBreakerSours

Thanks for the tip, but my model contains 3D elements and i want to simulate the complex behaviour of a foam.
Do you think it's still the best way ?

It will not work with 3D 3D elements.

OK,
thank you, anyway!
