The Frenkel–Kontorova–Tomlinson model is used to study the interface between two rigid sliding bodies. It consists of a chain of

n

equal particles of mass

m

connected by springs of strengths

κ

and damping force

γ

proportional to velocity. Each mass is coupled with a spring to the body at the top that moves at constant velocity

v

. The interaction with the body at the bottom is represented with a periodic potential of amplitude

b

, with

c

equal to the ratio of lattice constants. Open boundary conditions are used.
