Data analysis-elastic properties computational

Hi,

TexGen only uses one of the methods to calculate volume fraction. If you've put in fibres per yarn and yarn diameter, that is enough.

Your .eld file looks fine and the Vf looks fine.

hi,
thanks you very much! all are correct, but the results are not correct. I don't know why, This method has some secrets that can not be found yet.
very very sad. I will try again.

hi,
Nowaday I have 2 questions, I hope you can help me.
the first: I show in the picture. I was very surprised when it came to default in the software, v13 always different v23 and v12 always = v13. With default I have seen v13=v23.
the second: If I want change tm of the matrix in the picture 1, how to change this parameter?

Hi,

The expectation would normally be that the user would replace the default values with the correct values for their particular material. You can easily change the values if you want to.

You would change the value of tm in your illustration by changing the size of the domain as described here: http://texgen.sourceforge.net/index.php ... ide#Domain

Hope that helps,
Louise

Hi,
Thank you for your helpful, I want ask you in this picture attachment in here
where G12=Gxy, G13=Gxz, G23= Gyz, v12=vx...
this define when caculate in Abaqus are correct or not corect? If I change G12=Gyz and G23=Gxy, v12=vz and v23=vx. I have got good results
I'm very skeptical about these definitions.
thanks

Hi,

As I said previously these are just default values which it is expected that a user will change to their correct values. As the yarns specified by the user are unknown then there is no way of predicting correct input values for these - they are basically given by way of example.

hi,
thanks so much.
I want to try again with problem with other model such as this model, but I can't make it use 3D Weave after that use orthogonal, Can you help me.
thanks

Hi,

I'm sorry, but I don't understand what you're asking here.

Best regards,

hi,
I'm sorry, My Eng not well. I want to create this model. Can you help me.
thanks

Hi,

Please see the User Guide here: http://texgen.sourceforge.net/index.php ... e#3D_Weave for information on how to create 3D weaves.

Best regards,
