Localized mode in the bandgap of elastic metamaterial rod with end-coupled inertial mass

Key Points

• The localized mode occurs within the bandgap, which means it can trap energy in specific locations within the metamaterial rod.
• Experimentally, the gap was characterized across a range of inertial mass configurations, showing significant effects on mechanical properties.
• Assessment using the concept of elastic metamaterials provided insights on how the inclusion of inertial masses influences vibration behavior.
• Highlighting the need for further analysis to explore practical applications in vibration damping technologies.
