Abstract
Fracture experiment were carried out on unidirectional glass epoxy composite material with the presence of a crack parallel to the fiber direction. Fatigue tests were performed using tensile split specimens, the crack being parallel to the fiber direction. Split specimens loaded in fatigue tension parallel to the fibers were used. A damaged zone consisting in fiber bridging the major crack was observed and microfractographic observations revealed that the crack extension lad to mode one fracture mechanism. A three dimensional finite element method was employed to calculate the values of the strain energy release rates.
Crack growth rates versus ∆K1 and ∆K2 were studied and compared to those of pure mode I and mode II obtained with DCB specimens. It was shown, that this “analysis” corrolate microfractographic observations.
