“…The damping ratio was obtained by Equations (2) or (3) [ 34 ] or by using the modal analysis software. The storage modulus, complex modulus of elasticity and loss factor were calculated according to Equations (4)–(6) [ 35 , 36 , 37 ]. The results, which are shown in Table 2 , demonstrate the dynamic properties of the surface composite beam with respect to the base aluminum alloy.…”

In the present work, Aluminum Metal Matrix Surface Nano Composites (AMMSNCs) were manufactured using Friction Stir Processing (FSP). Moreover, the fabricated surface composite matrix was exposed to a different number of tool passes with different processing parameters. The tensile test and microstructure examinations were used to study the mechanical properties of the composite surface. The dynamic properties were predicted using modal analysis and finite element methods. After this, dynamic characterization was achieved by combining the numerical and experimental methods to investigate the effects of changing the number of passes on the natural frequency and the damping capacity of the AMMSNCs manufactured using FSP. The results indicated that the damping capacity and dynamic behavior improved with an increased number of FSP passes.
