An important feature of this microfibrillar model, and the load transfer conditions it
implies, is that the fiber modulus is independent of the crystallite length-to-
diameter ratio (i.e., aspect ratio). An alternative mechanical model of a fiber
involves ...

From the R-curves (crack resistance curves, i.e., J vs. Aa), where Aa is the
subcritical crack extension in static loading), J/c can be read by graphically
finding its intersection with the blunting line (J = 2 ay . Aa, where <ry is the yield
strength).

It was also shown that a term analogous to J/c namely the energy for damage
initiation, defined as the area under the load-displacement curve up to the load
maximum, increases with increasing crystallinity for PET. The same trend was
found ...
