About materials orientation errors

[NEROOO]

Hi,

I made a 2D-model with different material orientations, but after submiting it says that “ # elements have incorrect orientation. The third axis should be in the hoop direction.”

And my .inp file for the orientation was defined like below:

*************************************************************************
*Orientation, name=Ori-1
0.636173,0.486609,-0.598745,0.708940,-0.674890,0.204762
3,0.
*Solid Section, elset=face1, Orientation=Ori-1, material=a
*************************************************************************

It has cost me week to find way to solve the problem... looking for help!

Thanks a lot!

When user defined orientation is applied to 2D solid elements, it can only redefine X and Y directions. The third direction can't be modified (Z for plane stress/strain elements, θ for axisymmetric elements). This is explained in Abaqus documentation chapter "Orientations" (paragraph titled "Use with two-dimensional solid elements").

Thanks @FEA way!

I change the orientation defined like this:
*************************************************************************
*Orientation, name=Ori-1
0.636173,0.486609,0,0.708940,-0.674890,0
3,0.
*Solid Section, elset=face1, Orientation=Ori-1, material=a
*************************************************************************

Still shows error...did I get wrong about the explains in documentation?

Need help again!
