Hello everyone,
I'm using Abaqus in explicit. I know how to use cohesive surfaces in 3D explicit (general contact => individual property assignements) but in 2D explicit I can't define general contact, I have an error :
"CONTACT cannot be defined on 2D element facets. If the model contains 2D or axisymmetric elements then *CONTACT INCLUSIONS, ALL EXTERIOR cannot be specified, and the first surface name on each data line under *CONTACT INCLUSIONS or *CONTACT EXCLUSIONS must not be blank"
Someone know how to define cohesive surfaces in 2D explicit ?
I will be very grateful if someone can help
Alternatively, you can create a 3D model with one element in z-direction everywhere and apply appropriate boundary conditions in the z-direction to make your model effectively 2D. It's a bit wasteful, but may help with difficult surface modeling.

you can't use general contact in 3D modeling, instead you can utilize surface to surface contact. to use this contact, go to interaction module then create a surface to surface interaction. here you can define lines as surfaces.

I know for surface to surface contact but you can't use it with cohesive behavior.
Yes, it's what I did (3D model blocked in 2D) and it works nicely !
Thank you !
