Relationship between surface energy and E
A study of fracture mechanics has shown that the fracture energy directly correlates
with adhesion, which in turn is equal to the γ
c
of the elastomer. Therefore, adhesion
correlates with (Eγ
c
)
1/2
, better than with surface energy or E considered alone
(
Figure 2.11
) [9].
