  Friction impacts a wide range of fields, spanning engineering, geology,
biomechanics, and numerous others. As a fundamental force, it influences
various aspects of our daily lives and industrial processes across multiple
disciplines. To understand how adhesive friction seemingly breaks the size
limit dictated by the fracture theory, here we investigate the sliding of
elastic solids adhered to a rigid surface via multiple adhesive springs. With
the consideration of random re-attachment of detached adhesive springs, we find
that the shear-off force of the interface can significantly exceed predictions
made by the fracture theory, with substantial adhesive forces distributed
across the entire interface. Through this observation, we identify multiple
adhesive fronts closely aligning along the interface, exhibiting similar force
profiles. Moreover, the number of these regions seems to generally increase
with the interface size, resulting in a linear rise in the calculated shear-off
force with interface size. Therefore, we conclude that the close accumulation
of multiple adhesive fronts along an interface aids each other through random
healing so as to erase the size effect of the fracture theory, which offers
valuable insights into understanding the phenomena associated with adhesive
friction along an interface in various fields.
