Mr. Zeng,

I wrote a paper a couple of years ago. It used Euler Angles. Hopefully, you may find it helpfull:

Viscoplastic OR elasto-viscoplastic simulation

T.ZENG — Sat, 14 Nov 2009 10:29:52 -0500

When reading papers about visco-plastic or elasto-viscoplastic simulation, all authors only say that the orientation of grain used in the simulation can be randomly generated, and does not refer to how to generate them. I know the orientation of grain can be expressed by Euler angles (phi1, ph, phi2), but can someone give me advice how to generate euler angles?
