Hello dear FOAMers!

Stress components order in Cartesian coordinate system is:
[tau(xx) tau(yy) tau(yz) tau(xy) tau(xz) tau(yz)]

If the problem be axisymmetric (cylindrical coordinate system) and was solved in 2D geometry (wedge geometry) what is stress matrix? Is it the bottom matrix?

[tau(zz) tau(rr) tau(teta teta) tau(zr) tau(z teta) tau(r teta)]

notation!

related axes in 2 coordinate system

X --> z
Y --> r
z --> teta
