The full potential of composite materials has not yet
been realised. This is
due to lack
of fundamental understanding and a lack of confidence in
particularly for primary structural applications.
Innovative design tools are

is an essential goal for industry to ensure competitive
position in the next
advanced structures and components.
The objective of this literature study is to examine the
predictive methods for the strength of a cracked
Especially methods based on fracture mechanics are
Due to the fracture behaviour of composites the problem
is very complicated.
the work reported in literature has been done to assess
the effect of
the behaviour of a fiber-reinforced composite. This
creates the basis for the
general predictive methods for strength and lifetime.
Also, some similarity can
with the analyses of glued joints.
Finally, the special techniques required to numerically
determine the effect of
delamination on the strength of a fiber-reinforced
composite laminate are
