Fabric Volume Fraction

Post by ghaith »

Hello
I'm new with TexGen :oops: , i'm working on mechanical behaviour of a textile composite unit cell, i m trying to study the Influence of Fabric Volume Fraction ,i managed to change the Vf in texgen by manipulating the yarns props , but when i import the file(dry fiber) in abaqus and after a tensile test the output data didn't change compared to the original cell.Any help please ?

Hi,
I'm afraid that I'm not an ABAQUS expert so can't give you a clear answer to your question. The volume fraction information is output in the .eld file so you need to make sure that your simulation is utilising that information. You would probably be better finding someone who is more of an ABAQUS user who would be able to help you interpret simulation results.

Sorry not to be more help,
Louise

Dear Louise, thank you for the quick response.
I have another question , is it possible to create a fabric with a big dimension , like 200mm*50mm .how to make sure that i managed the right dimension .

Hi,
I assume that you mean that you'd like to create a fabric with a large number of repeats of the weave pattern? In this case you need to specify the smallest repeat of your weave pattern, specify repeat vectors and then set the domain to the size you need for your complete model (200x50mm).

It will help in creating your models if you understand the theory behind the modelling. I would suggest that you look at the User Guide http://texgen.sourceforge.net/index.php ... ide#Domain for information on how to set up a domain and take a look at the modelling theory either in Martin Sherburn's thesis http://eprints.nottingham.ac.uk/10303/1 ... -final.pdf or in one of the tutorials on GitHub eg https://github.com/louisepb/PurdueWorkshop2019

(You may find that rendering of large numbers of repeats is slow if you don't have a reasonably high-spec computer)

Hope that helps,
Louise
