composite material and fiber angles for 3D elements

Altair Forum User

Hi every one.

 

I was working for a 3D model, where i want to assign the composite material like e-glass epoxy with different fiber angles at different regions (for example like leaf springs). I wanted it to do with 3D elements, with including the contact non linearity. Can it possible, i have done for 2D elements by creating the plys and assigning the thickness. but looking forward to do over with 3D elements.

 

please suggest.

 

Thanks & regards,

Hi Ashok,

 

Do you know about MAT9ORT material card?

 

This can be used to model orthotropic material models with solid elements.

 

Please refer to MAT9ORT or MAT9 material cards in HyperMesh

yes Mr.prakash,

 

we can use the MAT9ORT card for creating the material. but my query is how to assign the fibers direction (I mean like fiber angles in ply while creating the laminates for 2D elements). Can it possible to create a 3D element property which contains the fiber angle incorporated. And, how to seperate the elements for different fiber angles like plys.

 

Thankd & regards.

Ashok,

 

you can orient the solid element in the PSOLID propertry.

 

for example, I have 4 plies {0,45,-45,90} which are solid element. 

 

So, I create 4 properties one for each ply and four coordinate systems one for each orientation (4 coordinate system 0cs, 45cs, -45cs and 90cs)

 

In each property, call the coordinate system.

 

card edit the PSOLID property and change the CORDM to user and select the coordinate system which will the ply orientation.

Hi prakash,
 
Thanks for your reply, 
 
I have done the same as you explained. created 4 psolid properties and updated the coordinate systems, everything is fine, but hot to view the fiber direction, and how to judge which axis it has taken for orientation.  Please find the attached .hm file send to your drop box, and have a look on 3D model. please suggest me how to view the fiber angle direction for 3D elements.

 Ashok,

 

Please try the script ID 382 available @ http://www.altairhyperworks.in/Script-Exchange.aspx

SSnell

What is the latest working script for this function? I believe I've found the latest script, but can't seem to make it work properly in 2017.2.

 

Can the elements be given the 2-axis of a cylindrical system?

 

Thank you
