We
have so far used
. It is defined as Caucy stress tensor given by,
=Cauchy
stress tensor (Force/area in the deformed geometry)
We
know for equilibrium equation
Define
two other stress tensors, first and second Piola-Kirchoff Stress tensors
Three
different stress measures
We
will denote
as
first P-K and
as
II P-K stress
