Summary: The paper deals with the one-parameter family of Gordon-Schowalter objective derivatives including the Oldroyd, Cotter-Rivlin, and Jaumann derivatives. For a simple shear, movable bases are found in which the considered differential operators are reduced to the total time derivatives of the tensor components. For all derivatives of the family under consideration, except for Oldroyd and Cotter-Rivlin derivatives, the basis vectors lying in the shear plane rotate with a certain period changing their length and mutual orientation.
