In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

Flexible manipulation of elastic and acoustic waves through phononic meta-structured
materials (PMSMs) has attracted a lot of attention in the last three decades and shows a …

Inspired by crystallography, the periodic assembly of trusses into architected materials has
enjoyed popularity for more than a decade and produced countless cellular structures with …

Artificial auxetic materials with negative Poisson's ratio enable distinctive elastic response in
the direction orthogonal to the loaded direction, ie shrinking when compressed and …

Mechanical cloaks can hide objects and make them unfeelable by reproducing the
surrounding displacement field without the objects and cloaks. In the existing works …

Metamaterials, man-made composites that are scaled smaller than the wavelength, have
demonstrated a huge potential for application in acoustics, allowing the production of sub …

The topological derivative method is recognized as a robust numerical technique in
engineering applications such as topology optimization, inverse problems, imaging …

This paper proposes a macro–microscale topology optimization approach for constructing
compliant mechanisms with deterministic mechanical characteristics based on the essential …

Various strategies have been proposed to achieve invisibility cloaking, but usually only one
phenomenon is controlled by each device. Cloaking an object from two different waves …

An analysis of the symmetries characterizing the micro-architecture topologies and the
elastic material properties is performed. The goal is to elucidate a systematic procedure that …
