FEA composite material

FEA composite material

FEA composite material

(OP)
Hi I'm trying to assign composite material to my component (car front bumper which is not just flat surface) which has material coordinate not align with global coordinate system (when u see in abq viewer). I'm using
*material, type=engineering constants
I need my fiber direction (E1) align with material X coordinate. z normal to the surface.

How do I use transformation or orientation
Please advise ASAP

I have hypermesh as a preprocessor

Thanks in advance

RE: FEA composite material

Hmmm...I'm not familiar with Abaqus, but since you are still aligning with a global axis, you should be able to properly input the physical properties so that the analytical work.  However, there should also be a method for orienting the laminate to the global coordinate system.

Your elements will have a default primary direction and a default normal.  Figure out these directions and you should be able to reorient them appropriate.  Most FEA packages project a vector onto a surface, so if your element is not in, say, the X-Y plane, you may still be able to orient the laminate with an x-vector (1,0,0) and have it work for the entire bumper.

RE: FEA composite material

I think the OP wants the coordinate system of the element.
