Abstract
The plane creep of a free surface in an isotropic incompressible viscous fluid is shown to be kinematically reversible under cyclic loading about zero mean. It is concluded that, when kinematically irreversible free surface motion is experimentally observed in materials which show no apparent history effects, the phenomenon must be caused by three-dimensional deformation.
