Abstract

In
this paper, a numerical study of the behavior of fatigue cracks of damaged
composite repaired aeronautical structures was presented. Various parameters
have been highlighted such as effect of the dimensions and mechanical
properties of the patch as well as the orientation of the fibers and the effect
of the dimensions and mechanical properties of the adhesive. Two geometrical
models have been proposed in order to see the influence of the crack position
and the overall failure behavior under fatigue stress of the damaged structure.
The results on the different geometric models of cracked plates and fissure
plates from nicks show that composite patch repair is an effective technique
for increasing plate strength, decreasing stress concentration and prolonging
their service life.
