(b) The maximum load P
max
increases with increase
of interfacial fracture energy G
f
and the Young’s
modulus of fiber E
f
;
(c) The shear stress and crack propagation is different
in the pull-pull and pull-push fiber-matrix pullout
model. In general, load-carrying capacity of pull-
pull pullout model is larger than that of pull-push
pullout model.
