where
UE is the elastically stored energy
UM is the mechanical energy associated with the applied load.
US is the total surface energy = wApa2
The JKR equation is given by:

Fundamental Assumptions of the JKR Theory
1.The deformations are elastic.
2.The contact radius is small compared to the particle radius.
3.All interactions are localized to within the contact region, i.e.
there are no long-range interactions.
