Popis: In the present work, the problem of the semi-infinite strip with traction-free lateral sides is revisited, in order to examine the displacement profile across the semi-infinite strip under an arbitrary normal load distribution on its end. Although the solution of this problem is important even for practical applications (e.g. the prediction of the rocking motion of deformable bodies), only numerical solutions exist until now, which are cumbersome to implement for such cases. In this paper, the displacement profile of the semi-infinite strip under a concentrated normal load is approximated with analytical functions, which must exhibit specific properties. These results are then extended to arbitrary normal load distributions and characteristic cases are presented. Finally, the problem of the determination of the stress distribution across the interface between a deformable rocking body and its base is solved based on the previous derivations.
