Abstract/Summary Tidal deformation of the Earth is normally calculated using the analytical solution with some simplified assumptions, such as the Earth is a perfect sphere of continuum media. In addition, the existing analytical solution cannot describe the rotation variations of the Earth due to tidal effects. We propose an alternative way to calculate the tidal deformation and rotation of the Earth using a finite element method based on our finite element code recently developed, which has no any limitations on such as the shape and material properties of the Earth. The tidal deformation and rotation of the Earth due to the Moon was calculated for various different earth models and compared with each other. The preliminary results demonstrate that the geometric shape and material properties of the Earth have obviously different effects on the tidal deformation and rotation of the Earth, which also depends much on the relative location of the Moon, i.e. the relative loading direction.
