Elastodynamical properties of Sturmian structured media

M. Lazaro et al.

Summary: This paper investigates wave propagation in structured media with quasiperiodic patterns and proposes a methodology based on Sturmian sequences for generating structured mechanical systems. The bulk spectrum is obtained and analyzed for its fractal nature. Three numerical examples are presented to validate the theoretical results, showing different shapes but sharing features explained by the theoretical setting.

A novel hybrid-honeycomb structure: Enhanced stiffness, tunable auxeticity and negative thermal expansion

Xiang-Long Peng et al.

Summary: A novel hybrid-honeycomb structure with enhanced stiffness is proposed, and its effective thermoelastic properties can be widely tunable by tailoring the microstructural geometry and the constituent materials. The structure can be designed to concurrently possess an enhanced stiffness and a high degree of auxeticity and negative thermal expansion by properly choosing the geometrical and material parameters.

Seismic metamaterials with cross-like and square steel sections for low-frequency wide band gaps

Kai Zhang et al.

Summary: This study investigates the propagation of Lamb waves in seismic metamaterials assembled using periodically arranged cross-like and square steel sections in a soil medium to assess the feasibility of their use for seismic wave attenuation. The results show that seismic metamaterials with three complete band gaps below 20 Hz are of particular interest for low-frequency vibration control, with those composed of square steel sections exhibiting a more favorable performance in terms of wider band gaps. The study provides a new way to build seismic metamaterials by designing the volume fraction and steel section shapes to provide ultra-low and broad-band frequency vibration isolation capabilities that will allow the shielding of seismic waves in specific frequency ranges.

Investigation of novel 3D-printed diatomic and local resonant metamaterials with impact mitigation capacity

Youchuan Zhou et al.

Summary: A novel dual local resonance metamaterial chain is designed and fabricated for wave attenuation and impact mitigation purposes, with an extended bandgap through both local resonance and diatomic resonance mechanisms. The optimized design shows excellent performance in wave attenuation and impact mitigation, with the best transmission rate driven down to 0.2 compared to a design without resonators at 0.48.
