... material with a folding partition. Herein, by introducing a folding partition in a reentrant honeycomb, we proposed a class of 3D closed-cell plate-based mechanical metamaterials with negative Poisson's ratio (NPR). Ultrahigh stiffness, 36% greater than the Hashin–Shtrikman upper bound, and excellent load...

...Michael Bonthron; Eleonora Tubaldi Mechanical metamaterials with multiple stable configurations offer a promising avenue for the design and development of adaptable materials with unprecedented levels of control over physical properties. Specifically, arrays of bistable beam elements represent...

... computational mechanics mechanical metamaterials vibration wave propagation Granular crystals are composed of a tightly packed collection of particles which interact by exchanging forces and moments through their geometric contacts [ 1 ]. Highly nonlinear evolution in their contacts enables granular...

...Hanxun Jin; Horacio D. Espinosa Mechanical metamaterials, whose unique mechanical properties stem from their structural design rather than material constituents, are gaining popularity in engineering applications. In particular, recent advances in self-assembly techniques offer the potential...
