“…Different approaches have been attempted to improve fracture toughness and delamination resistance of composite structures: this demands an understanding of composite failure mechanisms [15,[25][26][27][28][29]. Zhang et al found that interlaminar fracture toughness and interlaminar shear strength of flax/glass fiber reinforced hybrid polymer composites (HFRP) were higher than glass fiber reinforced polymer composites (GFRP): this led to improvements in the mechanical properties due to the excellent hybrid performance [30].…”

In this study, flax fiber reinforced and flax/basalt hybridized vinyl ester composites were produced and their interlaminar fracture toughness (mode II) behavior was investigated using the three-point bend end-notched flexural (3ENF) testing. From the results, the average of the maximum values for each group of specimen obtained for critical strain energy release rate G IIC and stress intensity factor K II for flax/vinyl ester specimens were 1,940 J/m 2 and 134 kPam 0.5 . Similarly, G IIC and K II values recorded for hybridized specimens were 2,173 J/m 2 and 178 kPam 0.5 , respectively. The results for the flax/basalt hybridized composites exhibited an improved fracture toughness behavior compared to flax/vinyl ester composites without hybridization. The cohesive zone modeling (CZM) was also used to predict the delamination crack propagation in mode-II in laminated composite structures. After the experimental study, the 3ENF specimens were modeled and simulated using ANSYS. The CZM/FEA results were in reasonable agreement with the experimental results.

“…For this study, linear elastic fracture mechanics tests were evaluated for K IC according to ASTM E 399 using the initial notch depth method. The stress intensity factor for a beam under TPB was developed according to linear elastic fracture mechanic by Tada et al [7][8][9][10][11] This method was based on the calculation of the critical stress intensity factor using the initial notch depth method. According to this method, the equation of the mode I stress intensity factor is…”

Steel fibre reinforced Zn-5Al alloy (Zamak 5) metal matrix composite beams with different volume fractions of steel fibres were produced with varying notch to depth ratios. The fracture and mechanical properties of the specimens were investigated for their mode I fracture behaviour using three point bending tests under static loading at room temperature. Steel fibres with contents of 1, 2 and 3% of the total volume of Zn-5Al alloy were used as matrix materials. The critical stress intensity factor was determined using the initial notch depth method.

“…Their experimental results showed that gradual fiber fractures were observed as the number of cycles increases. Wang et al [14] examined very long life fatigue fracture behavior of Al 7075 (T6) and Al 6061 (T6) and observed that fatigue failure in Al alloys was ascribed to the formation of fatigue voids, their growth and coalescence, and the subsequent formation and propagation of macroscopic cracks, Avci et al [15] determined stress intensity factors by using compliance and J integral methods for steel fiber reinforced concrete composites. Erkendirci et al [16] investigated the fatigue and fracture behavior of a woven steel-reinforced high-density polyethylene composite having a MT specimen with through thickness crack.…”

Fatigue crack growth and related damage mechanisms were investigated experimentally in a stainless steel/aluminum laminated composite with middle through thickness crack, and two different fracture mechanics approaches applied to the composite to reveal their differences under fatigue loading. The laminated composite material, which has a unidirectional continuous AISI 304 stainless steel as fibers and Al 1060 as matrix, was produced by using diffusion bonding. Fatigue tests were conducted in accordance with ASTM E 647. The relationships between fatigue crack growth rate (da/dN), stress intensity factor (AK), and strain energy release rate (AG) were determined; and damage behavior was discussed. Both linear elastic fracture mechanics (LEFM) and compliance method were used, and the results were compared with each other. It is found that as the crack propagates, the LEFM overestimates the AG values. Interlaminar and fiber/matrix interface damage were evaluated by fractographic examination.
