Abstract
An expansion for the structure factor of a simple liquid undergoing planar Couette flow is extended to tensor rank four. The coefficients are evaluated by the methods of nonequilibrium molecular dynamics (NEMD) for a soft sphere fluid at 7/8 of its freezing density. Intensity plots are constructed and it is shown that the fourth rank contribution to the structure factor is significant for a reduced shear rate of one.
