Material Orientation Method

Altair Forum User

Hello,

Attached you can find the model I am working on. It is 3d tetra meshed, after meshing i intend to apply material orientation. But i have some doubts, I select the material orientation as by vector, i wanted to know what coordinates should i define for N1,N2,N3 and base so that it will define the material orientation in 0,45 and 90 degrees or how do the coordinates of N1,N2,N3 work for any defined angle.

Thanks in advance

Hi Amey,

 

N1 and N2 defines the direction and N3 along with N1 and N2 defines the plane. 

 

Here is a sample video. This is purely for demonstration.

Hey Prakash, thanks a lots for the reply. 

 

I have another doubt,

I am working on a 3D tetra meshed model, where i want to assign the material with different fiber angles. I wanted it to do with 3D elements, with including the contact non linearity. Is it possible. I know i can can orient the solid element in the PSOLID property. 

 

But how can I create 3 properties and 3 coordinate systems one for each orientation (4 coordinate system 0cs, 45cs, and 90cs) I dont know how to create new coordinate system and how to apply them, how can i create different coordinate systems and how can i apply it to my part. Also I dont just need for the above mentioned 3 angles, i will need it for any angle possible, so it would be good if you can suggest me on that as well

please suggest.

 

Thanks & regards,

Amey

Hi Amey,

 

Why you want to use solid elements and why tetra mesh?

 

You can use the existing system to orient elements.

I am trying to simulate the additive manufacturing process, so i have to use solid elements and along with that 3d auto tetra mesh is best for solid elements, as i want to do an automesh.

And is it not possible to create different coordinate systems (with different orientations) for solid elements, is it just possible with plies?

From latest version 2017 you can assign material coordinate system to solid elements.Refer CORDM data in PSOLID card.

Hello Rahul,

 

Thanks a lot for the reply. Yes I know that thing, I want to create coordinate systems with different orientations and then assign them separately, I dont know how to create the coordinate systems with different orientations (for eg. 0degrees, 45degrees , 90 degrees so on). How can i create it?

 

Thanks and Regards,

Amey
