Abstract: The displacement vectors caused by the tide-generating force are different for different points inside the earth, hence tidal strain and stress fields are formed inside the earth. In the study of the relations between the earthquake and the earth tide, it is necessary to know the time and space distributions of the tidal stress field inside the earth. Homogeneous spherical elastic earth model is the first approximation of the real earth in the approach to study the earth tide, this paper gives a numerical method to calculate the stress field for such an earth model.

Key words: tide-generating force, earth model, tidal stress field
