“…For all the sample geometries, cracks were observed to propagate mostly stably without the crack jumps reported by many other authors [11,18,24]. During crack propagation, the transverse samples presented cracks that propagated stably in the middle plane (Fig.…”

“…The transverse samples, instead, showed the opposite behavior, presenting a rectangular section with a straight crack front but with a curved propagation path. The longitudinal samples, due to the filament winding production process, presented a higher layup angle compared to the longitudinal samples, which affected the calculated G Ic value [14,17,18]. The increase in the winding angle has also a considerable effect on the scatter of the evaluated value of G Ic as reported by Davies et al [14].…”

A common industrial production process for axially symmetric composites is filament winding. For this type of material, interlayer properties cannot be evaluated using the available ISO and ASTM standards because the curved surfaces and partially interwoven fibers of cylindrical parts can affect the results. This paper presents a special test geometry for measuring the critical energy release rate G Ic directly from actual filament wound products. Different specimen geometries were investigated numerically with respect to their stress state at the crack tip and tested experimentally. The results were compared against those of flat specimens tested according to ISO/ASTM standards and made from the same constituent materials as the original test pipe. Testing specimens taken from an actual filament wound pipe yields more realistic results of G Ic =1,220 J/m 2 than testing flat specimens (G Ic =330 J/m 2 ), especially made for fulfilling the test standard's requirements.

“…Several studies were already conducted on the mode I fracture of MD laminates with delaminations in θ/θ, θ/−θ and 0/90 interfaces [2][3][4][5][6][7][8][9]. The major problem is the development of intraply damage, often associated with extensive fibre bridging and non-linearity.…”

A study of mixed-mode crack propagation in bending-based interlaminar fracture specimens is here presented. A numerical scheme to simulate full crack propagation is proposed which makes use of interface laws relating interlaminar stresses to displacement discontinuities along the plane of crack propagation. The relation between interface laws and mixed-mode failure loci in terms of critical energies is discussed and clarified. Numerical simulations are presented and compared with analytical and experimental results.
