  • Constriction resistance
R_e = \rho/2a

(Single spot contact according to Holm; circular touching spot between clean

contact surfaces)

R_e = \rho/2Na

(Multi-spot contact according to Holm without influence between the N

individual spots)

R_e = \rho/2 x \sum a_i + 3 \pi \rho /32N^2 x \sum \sum (s_ij) i \neq j

(Multi-spot contact according to Greenwood considering the influence between

the spots)
