Abstract

When both sides of the contact spot are considered (Fig. 3.1), the total resistance is simply the sum of the resistances for each side of the contact. Therefore, if k 1 and k 2 are the thermal conductivities of the two solids in contact, then the resistance associated with a single contact spot is given by:
$$ R = F/(4a{k_1}) + F/(4a{k_2}) $$
(3.1)
$$ = F/(2ak) $$
(3.2)
where F is the constriction alleviation factor defined in chapter 2 and
$$ k = 2{k_1}{k_2}/({k_1} + k{}_2) $$
(3.3)
is the harmonic mean of the conductivities.
