Are there direction-dependent Constraints realisable in APDL (ANSYS 14.5)?

I want a line to be able to move in only negative x-Direction. If the line ever gets (back) to x=0 it should be constrained.

Is Anisotropy caused by using a Hardening-Model in ANSYS (Implicit)?

In a non-linear, implicit Process (2D), I start with anisotropic Settings and three E-Moduli for the three Directions of Freedom. When I use a hardening Model in ANSYS (Kinematic Hardening or...
