material orientation in case of laminated tube - NX6
material orientation in case of laminated tube - NX6
(OP)
Does anybody know, how to define material orientation for laminated tube in NX6? I´ve already done similar analysis for plate and I was succesful. I know, how to change material orientation using a vector or a coordinate system, but it seems, that the solver has a problem with the two remaining directions, that should be normal and tangent to the circular cross-section. I tried to change to the cylindrical coordinate system while meshing, but it didn´t work. Or, is the problem somewhere else?..:)
Thanks
Thanks

How do you want your material primary directions oriented? Along the tube axis?

Thank you very much for your reply. You´re right, I´m doing this FEM with NX6 Advanced Simulation. The material directions should be parallel to the tube axis. I´m using shell elements CQUAD8. I tried the last tip you suggested, but without any succes. Maybe also wrong material definition of the lamina - there is a lot of options and I have to check it properly. But again, thanks a lot

Thanks again for your advice! I'm quite sure about setting the mesh orientation :). As you said, I tried to mesh with CQUAD4. There were some warnings but the solution was done. But stil I had to think about putting on CQUAD8, which better represent the geometry. I'm not very sure because I haven't checked the results yet, but hopefully, I figured out the problem. After I defined the material orientation by selecting cylindrical CSYS I also assigned this CSYS to the nodes of the model as a nodal displacement CSYS. It removed error message 9137 from my simulation. I hope I'm not wrong.

Good to hear you're up and running.
