“…Metamaterials are artificially engineered materials displaying exotic behaviour not found in nature. Over the last two decades many applications of novel metamaterials have been demonstrated, but not limited to, ie; focusing/ controlling of waves [22], [23], subwavelength resolution imaging [24]- [26], sensing [27], cloaking [28], [29], negative refraction [30], [31], negative Poisson's ratio [32]- [35], seismic wave protection [36], vibration and sound suppression [37]- [40] etc. Another interesting feature of metamaterials is their ability to create bandgaps, i.e.…”

Cylindrical or circular rod-type waveguides are of much interest in applications such as measurement of flow, temperature, material properties in harsh environments, and also in medical diagnostics. However, multiple waveguide modes exist in such systems, out of which only some are of interest to certain applications. For example, L(0,3) longitudinal mode excitation can optimally transmit elastic waves into the test specimen and help in better sensing and measurement when compared to other modes within the family of longitudinal guided waves. This paper demonstrates the up-conversion of longitudinal modes within the family of guided ultrasonic rod waves (from L(0,2) to L(0,3)), which is of interest to certain waveguide transducer applications. The mode up-conversion is demonstrated using numerical simulations and experiments. An analysis is used to bring more insights and guide the design of the metamaterial in this process.

“…The dynamic stiffness matrix approach is used to calculate the natural frequencies for out-of-plane free vibration of three-layer symmetric sandwich beams by Gholami et al [51]. Jin et al [52] studied a low-frequency vibrating lightweight cylindrical honeycomb sandwich structure. Safaei [53] examines the damped vibrational behavior of a light sandwich plate subjected to a periodic force over a short period of time.…”

The aim of this paper is to present a proposed honeycomb core shape and compare it with a normal hexagonal shape core in a sandwich beam. The sandwich cores are simulated in finite element with different materials; aluminum and epoxy-carbon with six layers are used as face sheet and the results are compared to those obtained theoretically. Simulation of 3-point bending test is performed in commercial software ANSYS to verify the analytical results with the numerical ones. Hence, for simplicity one layer of the skin is used on the equivalent model of sandwich for lesser computational time and more accurate evaluation. Simulation of harmonic analysis of hexagonal core and proposed core shape is carried out in frequency domain to identify the core with less deformation under high frequency and it can withstand harmful effects. The proposed core shape model having the same cell numbers and material as the normal hexagonal model is compared with experimental results; it is observed that the proposed core shape model has good flexural stiffness, resonance, fatigue, and stress resistance at a higher frequency.

“…Droz et al [20] mounted local resonators on a curved panel to enhance the sound transmission loss at the ring frequency. Jin et al [21] designed a metamaterial cylindrical shell by introducing local resonators into unit cells of a traditional cylindrical honeycomb sandwich structure, and they studied the bandgap phenomena in such metastructures and found that within the bandgaps, vibration of the cylinder shell is considerably mitigated. It should be noted that metamaterials usually suffer the drawback of narrow sizes.…”

Thin-walled cylindrical shells are widely used in industries, such as the main parts of aircrafts, rockets, and submarines. Except for meeting the load-bearing capacities, such structures must also have good vibration and acoustic performances. However, it is still a challenge to control the multi-modal vibration of cylindrical shells at low frequencies. This study explores the cutting-edge local resonant piezoelectric metamaterials to control the low-frequency vibration of cylindrical shells. A novel cylindrical meta-shell with piezoelectric materials and digital circuits was proposed, and a multi-resonance transfer function is implemented in each digital circuit. A method to optimizing the parameters in the transfer function for the purpose of vibration reduction is developed. The vibrational characteristics of the meta-shell are numerically analyzed using the finite element method. Numerical results clearly demonstrate that by delicately designing the parameters in the transfer function, the meta-shell can reduce the peak amplitudes of the first five modes by 30 dB or more. Therefore, the proposed piezoelectric cylindrical meta-shell may open new opportunities in vibration mitigation of transport vehicles and underwater equipment.
