Cohesive behavior in abaqus

Cohesive behavior in abaqus

Cohesive behavior in abaqus

(OP)
Hello all,
I am trying to model a cohesive behavior between two paper fibres in Abaqus/static implicit, I have have defined the cohesive behavior with damage initiation and evolution between local surfaces. The simulation is done in 2 steps (compression and stretching), but it is diverging at the time that damage is initiated, I would be happy if anyone can help me solve the convergence issue.

I attached the input file for better understanding.
Thanks,

RE: Cohesive behavior in abaqus

Hi,

I run the simulation on my computer and it seems to be finish without a problem. At each increment, the total iteration is 1 and no severe discontinuity, which i believe indicate no convergence issues.
Am i missing something here?

Thanks for the help Mohcine,

It is strange! Which version of abaqus are you using? Could you send me your .odb file?

Best regards,
