Abstract
In this note, a representation is derived for a Cauchy stress response function that is necessary and sufficient in order that a simple material without memory be such that the principal axes of strain and stress always coincide. It is found that the material need not be isotropic. However, if the material is in addition hyperelastic, so that the work done in any cyclic motion is zero, it is shown that the material is necessarily isotropic.
