Abstract
Presents the study on the mechanical behaviors of composite laminates with both static and fatigue tests per
formed with different notched specimens and concludes with experimental results that ultimate strength and initial stiff
ness of various notched composite laminates is almost as same as un-notched ones but the fatigue life of notched speci
mens is much higher than un-notched ones. Compared with metals, composite materials are notch insensitive. The
properties measured by using bar type specimens can not represent the real properties of composite laminates. Notches
on the free edge may be helpful to the structure. The fatigue life can be predicted through theoretical models estab
lished using the residual stiffness model.关键词
