Orthotropic material properties for complex geometry
Orthotropic material properties for complex geometry
(OP)
Hello,
I would like to give some complex geometry orthotropic material properties. The best way I've found to model the geometry is to create spline and then create an area at the start of the spline and use the VDRAG and then VSWEEP commands to build the geometry and then mesh. Hopefully the attached image shows how it's done, the area has been highlighted in yellow, this is then dragged along the spline. The material properties in the plane of the area that is dragged are different to those along the drag line.
I'm struggling to work out how to get the material properties to follow the spline. I've had very limited experience using them many year ago but then I had to define a new coordinate system for each different element, in that case I only needed 3 or 4 coordinate systems but in this example I think I'll need one per element.
Any suggestions?
Thanks
George

I'm trying to model thermal conduction (initially maybe thermal stress later) in a helical coil of insulated wire. The wire follows the helical path shown in the drawing, in the direction of the wire the thermal conduction is very good, however in the other two directions due the insulation of the wire the thermal conduction is poor, several orders of magnitude lower than along the wire.
Thanks
