Plane Stress Conditions (b) (Cont'd)
For
thick geometry, like that of a prismatic cylinder or a thick dam
one of the
dimensions (e.g.

If we consider a section

away from the ends strain in the thickness direction
and
shear strains
vanish.
Only

Thus the state of strain is restricted to
plane.
We can see in the plane strain
