Tóm tắt

The essential idea of the principle of material frame-indifference - that material properties are frame indifferent, or constitutive functions are form invariant relative to change of observers - has been disputed recently by Murdoch in [1, 2] by the claim that the standard restrictions on constitutive functions can be deduced by purely objective considerations, without the requirement of form-invariance of the constitutive functions. The purpose of this paper is to show that such a claim is groundless by pointing out blunders in the specious proofs and by presenting counter-examples.
