“…Little attention has been devoted to FMLs containing a notch. [21][22][23][24] Khatibi and Ye 21 presented effective crack growth model to investigate the residual strength for various ARALL laminates containing circular hole. Wu et al 22 have studied the strength of Glare 4 with a circular hole and reported the delamination pattern and failure modes around the notch.…”

“…Some authors used finite element method to analyze elastic-plastic response and expansion of plastic zone in metallic layers of various FMLs. 23,24 The literature survey reveals that most of research works on FMLs containing a hole are limited to numerical modeling of structures with circular notch.

In this study, the blunt notch strength of a fiber metal laminate with circular, elliptic and square notch shape has been studied up to failure point. Investigation of the stress concentration does not give a good idea about the strength in anisotropic plates and a failure criterion should be employed to evaluate failure. Therefore, an analytical method has been developed to evaluate stress components and predict the failure around the holes with different shapes. In order to obtain empirical results, specimens were manufactured by alternatively stacking aluminum and E-glass-epoxy layers according to the Glare standard. Analytical results show that the yielding of aluminum layers is the damage occurring to the plate initially. As a result, after the onset of the plastic flow in metallic layers the plate is not homogenous anymore, and conventional analysis cannot not be applied. An analytical model has been suggested to inspect the behavior of the plate at its ultimate load and is verified by ANSYS simulation. Comparison of different models indicates that numerical and theoretical models agree well with experimental test results. Also, the effect of aluminum thickness on strength has been examined analytically.

This study aims to explore the open-hole tension of fibre metal laminates containing thermoplastic particles experimentally and theoretically. In this regard, a vacuum bagging infusion process has been used to manufacture glass and glass metal laminates. Further, the tensile strength and damage failure modes were predicted using the Abaqus software, finite element analysis (FEA). This prediction was performed under a tensile test for notched composite laminates. The results of experimental tests indicated that the notch sensitivity is very important in terms of fracture and failures of composites. Furthermore, the findings show that the fibre metal laminates are less notch sensitive than glass composite laminates because of enhancing the composite ductility. In total, 28% of tensile strength decrease has been achieved after having holes for glass composites while the reductions were only 22%, 15% and 13% for glass composite laminates that have one, two and three aluminium layers, respectively. This reduction also becomes 4% for glass composite laminates that have one aluminium layer and thermoplastic particles and they exhibit typical ductile damage failures compared to other laminates. Further, the findings of numerical simulation for tensile strength and damage failure modes follow experimental results both qualitatively and quantitatively for notched composite laminates under tension loading.
