“…Various hard particles such as titanium carbide [20], aluminum oxide [21], silicon carbon [22], carbon nanotubes [23], and graphene [24] have been incorporated into metal matrix composites. The literature indicates that most authors have investigated the mechanical and tribological properties, while only a few authors have investigated the frequencies on fabricated specimens made of different reinforcement materials.…”

In various applications such as plant mines or mechanical systems, machines in operation generate significant vibrations which are transmitted from the foundation to the surrounding environment and precision instruments. In order to minimize these vibrations, they must be either isolated, absorbed, or damped. The current study investigates the effects of an oil damper, passive vibration isolator, and absorbers (single and double) on the vibration frequency of a composite beam made of Al6061 (with 90% weight fraction) and SiC (with 10% weight fraction) produced through the stir casting process. Experimental analysis was conducted on the fabricated composite beam to investigate the frequencies of the fundamental vibration modes under hinged-hinged, fixed-free, and fixed-hinged boundary conditions. Results indicate that the absorber, damper, and isolator have a significant effect in reducing the amplitude of vibrations, resulting in lower frequencies compared to the main frequency. Furthermore, as the number of holes in the beam increases, the frequencies decrease due to a decrease in stiffness. The frequencies are higher for fixed-free end conditions without holes compared to other conditions. The oil damper was found to be more effective in reducing vibrations compared to absorbers and isolators.

“…23 The effect of temperature profile on dynamic characteristics of aluminum silicon carbide metal matrix composite was examined. 24 Non-uniform edge loading effects on dynamic characteristics of FG-graphene composite plate were investigated and found that graphene nanoplatelets distribution and volume fraction significantly altered the resonant amplitudes. 25 The effect of variable edge load and porosity on sound radiation characteristics of graphene nanocomposite plate were investigated analytically and given the optimized guidelines for graphene platelets and porosity distribution to achieve less sound power.…”

The influence of non-uniform heating on the anisotropic plate’s dynamic and acoustic response characteristics is investigated numerically. The effect of non-uniform heating on the plate is accounted in the form of pre-stress developed on the plate due to non-uniform heating of the plate. The influence of structural boundary conditions, nature of temperature variation, and level of temperature on vibration and acoustic response characteristics are investigated in detail. Thermal buckling strength and fundamental buckling mode are highly sensitive to the nature of temperature variation across the plate. Free vibration mode shapes of the plates with high aspect ratio and free edges are changing their pattern with an increase in temperature. The resonant amplitude of sound power radiated associated with a particular mode is dominated by vibration nodes and anti-nodes shifting relative to the excitation location. Further, an increase in sound power level with an increase in temperature is observed clearly in the lower octave frequency bands.
