| چکیده | ||
| 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. | ||
