In this research, effect of opening on the buckling of FMLs (Fiber Metal Laminate) is studied. Samples are made of a laminate, epoxy resin reinforced with four layers of woven basalt fibers, inserted between two Al plates. Different samples are prepared, tested and studied; one group without opening and the other two groups with circular openings of radii 10 and 20 mm. In all samples buckling is associated with de-bonding. Post-buckling behavior is studied. Plasticity in Al plates and damage in composite laminate are detected in samples with opening which make their repair challenging and risky. Nevertheless, repair of samples without opening are straightforward because of the fact that neither of the above phenomena are spotted in these samples.
