I am using[B] Abaqus/CAE 6.10[/B] to simulate a Debonding test (cohesive behavior for composite delamination).
I ran a Abaqus debonding simulation example (from Abaqus online documentation - [B]Abaqus Benchmark Manual[/B] - 2.7.1 Delamination analysis of laminated composites) importing an INP file available.
The Abaqus/Explicit three-dimensional model with [B]surface-based traction-separation behavior[/B] used the following surface [B]contact interaction properties[/B]:
- default Cohesive behavior
- XFEM-based LEFM (using VCCT) fracture criterion.
The following [B]ERROR message[/B] appeared after submiting the job:
The direction parameter is not available for *fracture criterion with surface-based cohesive behavior.
I tried to run the model without the XFEM fracture criterion and it went allright.
[B]Do anyone knows why cant I apply this fracture criterion in this DCB test?[/B]
Thank you for your time and attention.
