Cyclic response of ultra-lightweight pentamode metamaterials

Key Points

• The cyclic response characteristics of metamaterials were demonstrated using experimental data, highlighting unique mechanical properties.
• Significant findings revealed alterations in frequency response during cyclic loading, with implications for design stability and resilience.
• Assessment of the mechanical properties involved detailed experimental tests on pentamode metamaterials to observe their behavior under stress.
• These results may enable innovative applications in materials science, though real-world simulations are necessary for practical application.
