Abstract
A necessary and sufficient condition for a viscosity field to be steady in the spatial description when the motion is defined in a material description is derived. The derivation depends on an application of the theory of dynamical systems. Extension of the result to a velocity field, unsteady in one frame but steady in a second frame, is made and examples given, both in the spatial and material descriptions. Connections with motions with constant stretch history are explored. (A)
