  We run molecular dynamics simulations of folded graphene sheets and present a
procedure to measure the sliding friction in these systems based on the rate of
decay of a damped-harmonic oscillator. This procedure allowed us to study the
affect the size, geometry and the temperature of the graphene sheet had on the
ability to propagate the initial fold and the rate at which it settles to a
final 'fully-folded' equilibrium state. We offer simple rationalisations for
the relationships between the initial geometries of our simulations and the
friction values that emerge.
