Question

Material orientation setup

I am trying to figure out how to use the material orientation menu on creo parametric 2.0. I created a new orientation and selected my coord. system but I don't understand what the 1, 2, 3, X, Y, Z and "rotate about" are for. I would like my material to be oriented along the X axis. can someone help me set this up?

Thanks

Randy

Hi Randy

This contraption is just meant for people that accidentally define their material coordinate system in the wrong direction.

If you want your material to be oriented along the x-direction, the "1"direction must be the local x-direction as in this picture. If you happen to want the 1-direction to coincide with the local z, feel free to change the selection.

Hope this helps

Thanks Erik. I have the material orientation correct but I got a message saying orientation is ignored for isotropic material. Would using the same young's modulus for E1, E2, and E3 give me accurate results? I only have a modulus of 10400 ksi for my material.

Hi Randy

If you do that, you don't have to do that. To be more clear, if it is correct that E1=E2=E3, than the orientation doesn't matter and you can use isotropic material anbd you don't need a material coordinate system. In  stead, you can use that coordinate system to show stresses (σxx , σyy, σzz   ) where x and y and z are according to that coordinate system.
