Dynamic crack-XFEM
XFEM can be used in Abaqus for static analysis. I would like to use XFEM in implicit or explicit dynamic analysis.
I am using Abaqus version 6.13.
XFEM is allowed with static analysis in earlier Abaqus versions (6.9).
Newer versions have implicit dynamic analysis compatiblity with XFEM.
However, when I define an implicit dynamic step,
XFEM Crack Growth option does not appear in the Interactions section when 'Initial Step' is chosen. It appears only if a static/general step is chosen.
If 1)a static step is defined, and then a XFEM crack growth interaction is defined, and then 2) the static step is replaced with an implicit or explicit dynamic step,
I get the following error message after the work has run:
ERROR: THIS KEYWORD IS NOT AVAILBLE IN Abaqus/Explicit
LINE IMAGE: *enrichment, name=CRACK-1, type+PROPAGATIONCRACK,
Elset=ASSEMBLY_PICKEDSET6
Is XFEM only available with step-1>static/general in Abaqus standard/explicit ?
What is the way to create a dynamic crack ?
Thanks.
