Orthotropic material - 'element' or 'material' axis?

Hi

Quick question about using orthotropic materials. I've gotten the 'material axis' in the results environment to allign with what I would like to be the 'Local Axis 1'. This however does not correspond to 'element axis 1'. I's like to use tetrahedral elements, so it's proving impossible to have the 'element axis 1' allign with my desired 'local axis 1' of my orthotropic material.

Could someone please verify that the 'material axis' is the 'local axis 1' for orthotropic materials? Or help me uderstand how the 'material axis', 'element axes', and 'local axes' correspond.

Thanks,
Shannon

Hi,

 

As I understand it, there are a few axis to know inside Sim Mech. 1. Global 2. Element 3. Material 4. Layer(for composite laminae). I believe material axis shown in the results environment refers to the local axis 1 inside the material properties. This page has a good description on the orientation of the various axis inside the software. Hope this helps.

 

Regards

Thanks :smileyhappy:

I'd read all the documentation on composite elements, but hadn't checked the plate element page. I think we're correct to assume at the 'material axis' in the results environment is the 'local axis 1' in the material properties. The nomenclature is a bit confusing as one would assume that the 'local axis' is the elements local coordinate system.

Thanks for your help.
