Did you use Remote Displacement on the symmetry planes?  Delete that, it is wrong.


Use Displacement on the symmetry plane. 


For the long center plane, Z = 0 and for the short center plane, X = 0 the others being free.


Use 1/8 symmetry and cut the thickness in half and on that plane, the Displacement BC is Y = 0.


Then you can apply a non-zero displacement along the X axis on the 1/4 end face of the sample.
