Abstract
An elastic block on a substrate experiences a random pinning potential whic h breaks the lattice at the block-substrate interface into "correlated volu mes" (cells of size xi) that behave elastically independent and are pinned individually. We calculate the elastic coherence length xi and discuss its relevance for sliding friction and earthquake dynamics. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
