Notes:
The aim of this work has been the study of mode I delamination of multiply double cantilever beam specimens of glass fiber/epoxy. The results show an important influence of laminate lay-ups on delamination resistance. The value of GIc at the initiation of delamination varies with laminate curvature coupling Ky/Kx and Kxy/Kx. An empirical model describing this variation has been proposed. In addition, it is seen that the values of GIc at the initiation of delamination and at stable crack growth will be very different. The delamination resistance can be characterized by two constants: GIc corresponds to the initiation of delamination, and GSIp corresponds to the plateau of stable crack propagation. The correlation between experimental measurement and analysis of compliance and energy release rate results reveals significant three-dimensional effects.
