Orthotropic properties in cylinderical coord system
Orthotropic properties in cylinderical coord system
(OP)
Hi everyone,
I've a problem properly orientating a composite material in a cylinderical coordinate system, to explain:
The composites material orientation system is:
1 - longitudinal
2 - transverse
3 - through thickness.
For a Cartesian coord system, this corresponds to:
1 - x-axis
2 - y-axis
3 - z-axis
Which is OK.
But a cylindrical coordinate system, the internal mapping is:
1 - Radius-axis
2 - Theta-axis
3 - Z-axis
Which would mean for a composite the longitudinal material properties are mapped to the through-thickness axis, the transverse material properties mapped to the longitudinal axis and the through thickness material properties mapped to the transverse axis.
How do I change this mapping around to correctly reflect the material properties.
Thank you for your time.
Brendan

I had to bite the bullet and make a separate material.
I think its pretty weird there isn't the two or three lines of code necessary to change the internal axis designation from a conventional cylindrical coordinate system to one suited to composites.
