Long range elastic interactions friction

In the remainder of this section, we will first analyze the competition between local shear and long-range elastic interaction in the case of hard solids. One of the central questions is how one can determine the size of one BK block. Finally, in Section VII.B, the sliding motion of a soft elastic body with large internal friction on a corrugated substrate will be discussed. In the latter case, friction arises not only as a consequence of finite shear forces in the individual microcontacts but also because of the internal friction of the elastic medium.
