The adopted nutation series correspond to an elliptical uniformly rotating Earth with an elastic inner core, a liquid core and an elastic mantle. There exist nowadays a difference between the theoretical results and this theory. In this paper, we introduce the mantle inelasticity in the equations in order to give an idea of its contribution to the nutations.
