Modelling a Co-Bonding between Volume and Shell Elements to extract Shear Stresses (using Abaqus)

Modelling a Co-Bonding between Volume and Shell Elements to extract Shear Stresses (using Abaqus)

Modelling a Co-Bonding between Volume and Shell Elements to extract Shear Stresses (using Abaqus)

(OP)
I currently try to model a complex shaped metal part which is co-bonded to a composite layup. The metal part is modelled using 3D tet mesh and the composite is modelled using shell elements (with composite material property). I did already run the model by simply putting a "tie" between the tet (metal) and the shell (composite) mesh.

However, I should somehow extract the contact stress (shear stress, peel stress) between the composite and metal to make a comparison to experimental data I have.
Any suggestions how that could be performed? (I'm using Abaqus 6.14).

Thanks in advance,
Garm

The regular tie-constraint does not generate output. Define a contact pair, activate the adjust parameter in it and then use the tie option that becomes available there. In keywords it is *Contact Pair, adjust=0.01, tied. The 0.01 is just an example for an adjust value.

Or define a contact behavior with Friction=Rough and No Separation and use that in a contact pair.
