Abstract
Multi-layered composite materials with improved capabilities are fiber metal laminates ‎‎(FMLs). Damage to the composites, such as delamination, decreases their stiffness and ‎modifies the dynamic behaviour of the structures. Vibration analysis can be a good way to ‎forecast delamination since the loss of stiffness affects the natural frequencies, mode ‎shapes, and other structural features. In this research, vibrational analysis of aluminum ‎and mild steel-based carbon fiber metal laminates is considered with delamination. A total ‎of thirty-six fiber metal laminate specimens of 3/2 configuration with various ‎delamination areas and situated at various interfaces were considered for vibrational ‎analysis, which was carried out experimentally and by FEA software. The analysis is done ‎on healthy and delaminated specimens under clamped-free and clamped-clamped ‎conditions. The results demonstrate that the proposed method indicates that delamination ‎reduces the natural frequency of the FML. The decrease in natural frequency can be used ‎for damage detection, which will act as a base for an inverse problem.‎
