Optimization of vibration band-gap characteristics of a periodic elastic metamaterial plate

Yuanhao Xiong et al.

Summary: This article presents a design method for a periodic elastic metamaterial plate based on the locally resonant band-gap mechanism. The band-gap characteristics of the plate are calculated using the finite element method and validated through spectral element analysis and vibration experiments. An effective asymptotic optimization method is used to optimize the band-gap characteristics, aiming at specific frequency bands to achieve superior vibration reduction capacity.

A novel planar auxetic phononic crystal with periodic cookie-shaped cellular microstructures

Si-Hang Xiao et al.

Summary: A novel planar auxetic material is designed in this study by introducing a periodic cookie-shaped pattern to reduce stress levels and create a complete band gap at lower frequencies. The designed structure features a self-collimation effect and parameter analysis can help tailor optimal acoustic and mechanical properties for auxetic phononic metamaterials.

Design and Wave Propagation Characterization of Starchiral Metamaterials

Yajun Xin et al.

Summary: In this study, the wave propagation and band gap properties of a metamaterial with simple artificial topological properties made from industrially produced single-phase materials were investigated using the finite element method. The analysis of unit cell mode shapes and the systematic study of geometric parameters demonstrated that the band gaps of the proposed metamaterial could be reasonably predicted through the evolution of geometric parameters. Finally, the correctness of the band gap simulation results was verified by calculating the transmission characteristics of finite sandwich panel structures, indicating the potential application value of the proposed artificial metastructure in vibration and noise reduction projects.

3D chiral mechanical metamaterial for tailored band gap and manipulation of vibration isolation

Pengcheng Zhao et al.

Summary: This study established a dynamic model of a 3D chiral mechanical metamaterial to analyze the band structure and transmission response under different configurations. The results show that chirality can convert longitudinal waves into transverse waves, leading to vibration attenuation and the ability to predict band gaps.

3D chiral mechanical metamaterial for tailored band gap and manipulation of vibration isolation

Pengcheng Zhao et al.

Summary: This paper investigates the dynamic properties of a 3D chiral mechanical metamaterial, showing that the isotactic configuration converts longitudinal waves into transverse waves due to chirality, leading to vibration attenuation independent of band gaps. Band gaps appear in the syndiotactic configuration's band structures, and the vibration mode of ligaments can be used to predict band gaps. The study also demonstrates the potential for practical applications of vibration suppression using gradient and programmable design.

Phononic band gap optimization in truss-like cellular structures using smooth P-norm approximations

Leonel Quinteros et al.

Summary: The emergence of additive manufacturing and advances in structural optimization have led to the development of tailored cellular materials with complex architectures that show higher structural efficiency compared to traditional materials. Truss-like cellular structures, in particular, have great potential for lightweight applications due to their high strength/stiffness to mass ratio. These materials may also exhibit impressive vibration isolation properties known as phononic band gaps. The study focuses on the topology optimization of 2D truss-like cellular structures to create a material with outstanding vibration isolation at specific frequency ranges. The proposed formulation effectively addresses convergence problems associated with mode switching and repeated eigenvalues.

Enhanced Vibration Isolation with Prestressed Resonant Auxetic Metamaterial

Adrien Pyskir et al.

Summary: This paper presents a numerical and experimental study on a locally resonant auxetic metamaterial for vibration isolation, combining different mechanisms such as buckling, local resonances, and auxetism to enhance isolation properties. The study found huge bandgaps for the resonant case and confirmed strong isolation properties through experimental validation.
