RE: Re: plane stress/plane strain thickness

plane stress conditions are for cases where the geometry and loading are
configured that the stress in the thickness direction is zero.  Generally
this is for relatively thin sections but the thickness can be of any value.

Plane strain is for a geometry and loading where the strain in the thickness
direction gives zero or constant strain.  This is usually for a slice in an
essentially infinitely long object.

Also, are there any reasons why plane stress can be of any thickness
and plane strain to be set to unity?
