A Note on the Objectivity (Rotational Invariance) of the Stored Energy Density in Continuum Physics
This short note is concerned with the rotational invariance of the stored
energy density in continuum physics as a scalar function of a few vectors. A
simple derivation is presented for the determination of the general form of the
energy density in the case of a two-dimensional space. It is also shown that
the general form of the energy density so determined may be further reduced.
The three-dimensional case is also discussed.
