In continuum mechanics, Noll introduced the so-called principle of material objectivity,[6] which states that the constitutive laws governing the internal conditions of a physical system and the interactions between its parts should not depend on whatever external frame of reference is used to describe them.
"Principle of material objectivity" is now an obsolete term that has been replaced by principle of material frame-indifference.[7]
