Abaqus compaction script request.

[UOMO]

Dear all/Louis,

I am wondering if there is available any Abaqus script (based on the Output from TexGen) describing a procedure for compaction of the RVE. I do not know if this sounds familiar to you, but the intention is to simulate the preforming procedure by compacting the layers which results in distorted cross sections of the yarns. This is done by defining contact between yarns. Therefore, higher volume fractions can be achieved.
Thank you,
/UOMO.

Hi Uomo,

If you use the Abaqus Dry Fibre Export option in you can specify the use of compaction plates and a deformation in the z direction. The export automatically generates contact surfaces.

Hope that helps,
Louise

Thank you Louis. Is there any "trick" you use later on to incorporate the matrix surrounding the yarns (compacted)?

Any Abaqus script that uses the .inp generated to cause such a compression/incorporate matrix, etc. would be highly appreciated.

Hi Uomo,

I've just remembered that there is a script, Abaqus.py, included in the TexGen installation which reads a deformed textile back into TexGen. I think, however, that this doesn't work for newer versions of Abaqus as the output format has changed. It may point you in the right direction though.

Once you've imported back into TexGen then you can create a domain and use one of the other export methods to export both yarns and matrix.

Hope that helps,
Louise
