What do you mean by validated for CFRP?

Anyways, you can define the material in MATERIAL section as isotropic, orthotropic, or anisotropic.

Then, in SECTION Card you can define whatever number of layer thickness and orientation.

Check my attached files for example.

Hello all,

Thank you Ahmed H. Abdulaziz!

Do you also have a example for a solid structure (not shell)?

I need to transform a Abaqus file into a CalculiX input and I am not sure how to implement the CFRP part in Calculix.

I have three layers 90,0,90.

How do I give the exact Orientation. My elastic material behaviour is defined as

*MATERIAL, NAME=CFRP-Solid

*DENSITY

1580.,

*ELASTIC, TYPE=ENGINEERING CONSTANTS

1.695e+11, 8.58e+09, 8.58e+09, 0.28, 0.28, 0.45, 5.03e+09, 5.03e+09

2.96e+09,

From Abaqus I get following Input:

***SOLID SECTION, ELSET=FishBAC-1_CompositeLayup-1-1, COMPOSITE, ORIENTATION=FishBAC-1-Ori-1, STACK DIRECTION=3,

layup=CompositeLayup-1

1., 1, CFRP-Solid, 90., Ply-1

1., 1, CFRP-Solid, 0., Ply-2

1., 1, CFRP-Solid, 90., Ply-3

How can I define the orientation of the Section now and the number of Layers with there Orientation?

I would really appreciate your help!

Please, excuse me not response for your question but i demand you for help. I'm a begining with Calculix and i have a problem with orthotropic elasticic model.

If you are favorate for this tell me to send you the file .inp.

Thank you
