JKR and Other Adhesion Models
Pull-Off Force
The JKR model predicts that the force needed to remove the particle (the pull-off force) is given as

Contact Radius at Zero Force
The contact radius at zero external force may be obtained by setting P = 0 in Equation (1). That is,
|

Contact Radius at Separation
The contact radius at the separation is obtained by setting
in Equation (1). The corresponding contact radius is given by
