Abstract
The elastic deformation and adhesion of two con­
vex bodies that interact via surface forces of fi­
nite range is calculated self­consistently. Hertz
theory is compared to the result of an exponen­
tial repulsion, and it is found to be valid in the
limit of short­ranged forces and high loads. A
Lennard­Jones law is used to examine the clas­
sical theories of adhesion, which relate the sur­
face energy to the pull­off force, and their regime
of validity is explored. Explicit expressions are
given for the displacement prior to contact, and
