Material orientation of ply

Recommended Posts

Hi,

1. Is the material orientation of each ply the same? I assigned different material orientations to each ply, but I cannot get the expected material orientations.

2. How to assign material orientation to elements with ply (fiber) direction? I try to assign the material orientation to plies with the cooridinate systems each ply used in drapping operations. But I found the obtained material orientation is not coincident with the ply direction. The attached pictures  are the results of this test (for example, the directions in face A). I want to get the same directions, but I don't know how to do.

I see that you have given same orientation for both the plies. Please check.

Hi @mansin

 

Is there a reason for having two systems?

 

You can align material with one system and have different angles on two plies. Since the difference between the two plies is 120, you can have one ply with 0 and the other with 120

Hi, Prakash Pagadala

I cannot assign different material orientations to each ply element, although I set the ply angle of the two plies in one coordinate system. Are the material orientations in each ply of composite material's model the same?

Many Thanks.

@mansin Material orientation will be the same for any ply. Ply angle takes this as the reference for further orientations.
