DOI: 10.1063/5.0294140
Abstract: The integration of smart materials with external stimuli to tune bandgap properties has garnered significant attention in recent years. Magnetorheological elastomers (MREs) are particularly promising due to their controllable stiffness, which responds rapidly and reversibly… read more here.

DOI: 10.1080/15376494.2024.2383317
Abstract: Abstract To achieve multiple low-frequency topological interface modes (TIMs) while maintaining lightweight and load-bearing capacities in metamaterial beams, we propose novel topological beams equipped with double quasi-zero-stiffness (QZS) resonators. Following the introduction of the negative… read more here.
