Noise reduction is of critical importance in many engineering applications. One way to
achieve noise reduction is using acoustic metamaterials. However, traditional acoustic …

Thin-walled structures have been widely applied as energy absorption devices due to their
lightweight, high energy dissipating capability through large deformation, and low cost. The …

In this paper, an innovative bio-inspired multi-layered graded foam-filled structure (MGFS)
mimicking the characteristics of the human skeleton was proposed in an attempt to improve …

Mechanical metamaterials have unprecedented properties that contribute to the
development of science and technology. However, once the mechanical metamaterials are …
