debonding-cohesive zone modeling - abaqus- traction separation element 1

[lexarsmith]

Could any one please guide me how can I simulate the debonding behaviour (traction sepration elements) of the two cylinder type models in ABAQUS. It will be a life saving help from you.
Thank you!!!!

hi xerf, with the interface material of 0.01 thickness...

the initial increment time is 0.01 and also i put increment size as 1e-20.
Also the load is
time - load
0-0
0.5-5
1-10.25

but still i get the same error "too....increment"

the global seeding size is 2.

I also changed the meshing technique from SWEEP to the FREE meshing, but still the same problem....

Maybe you should try a finer mesh, a thinner interface part, just do not give up , mkay.

Hi brep

how do you assemble the orphan meshes of two concentric cylinders? Why cant I use the assembly-constrain-coaxial to put the concentric cylinder's orphan meshes?

Thanks

Create a csys on each of the orphan mesh parts. Use an edge-to-edge assembly constraint (using the appropriate axis from the csys as te "edge")
