The design of notched composite laminates is based on the averaged stress over
certain characteristic distance from the notch edge and the strength of the
corresponding un-notched laminate.
In practice, the notch geometry is not perfect
due to machining conditions and the mechanical properties of composite
The imperfections in notch geometry have a stochastic distribution.
On the other hand, tests on laminate coupons show that the un-notched strength
also has a stochastic distribution.
Accordingly, the characteristic length used in
design has a stochastic distribution.
Therefore, in order to ichieve a design with
a required reliability and safety, (i) the stress analysis of the notched lam...
