Mechanical couplings of 2D lattices uncovered by decoupled micropolar elasticity tensor and symmetry operation

We introduce a generalized methodology to uncover all mechanical couplings in 2D lattice geometries by obtaining the decoupled micropolar elasticity tensor. We also correlate the mechanical couplings with the point groups of 2D lattices by applying the symmetry operation to the decoupled micropolar elasticity tensor. The decoupled micropolar constitutive equation reveals eight mechanical coupling effects in planar solids, four of which are discovered for the first time in the mechanics' community.

Multiband homogenization of metamaterials in real-space: Higher-order nonlocal models and scattering at external surfaces

Dear colleagues, 

We invite you to read our recent article, which proposes a multiband homogenization scheme and has been accepted to appear in JMPS (https://www.sciencedirect.com/science/article/pii/S002250962200182X)

Metamaterials with Giant and Tailorable Nonreciprocal Elastic Moduli

Natural nonlinear materials, e.g., biological materials and polymers, are mechanically weak. It has been amajor challenge to develop a nonlinear material with potentialmechanical applications. Here, we develop a nonlinear elastic metamaterial with giant and tailorable-nonreciprocal elastic moduli. The metamaterial is designed with a microstructural axial asymmetry, which activated nonlinear microstructural deformations in the axial direction and microstructural residual moments.

Hinged-3D metamaterials with giant and strain-independent Poisson’s ratios

Current designs of artificial metamaterials with giant Poisson’s ratios proposed microlattices that secrete the transverse displacement nonlinearly varies with the longitudinal displacement, and the Poisson’s ratio depends on the applied strain (i.e., tailorable Poisson’s ratio). Whereas metamaterials with tailorable Poisson’s ratios would find many important applications, the design of a metamaterial with a giant Poisson’s ratio that is constant over all the material deformation range has been a major challenge.

Phononic canonical quasicrystalline waveguides

I am glad to present a recent set of papers highlighting the noteworthy properties of 1D periodic waveguides generated by a quasicrystalline sequence. The concept of canonical configuration explains how to obtain a periodic frequency spectrum and why this outcome is connected to trace mapping:

Snap-back induced hysteresis in an elastic mechanical metamaterial under tension

We combine experiment and finite element simulation and come up with a design of a mechanical metamaterial which demonstrates snap-back induced hysteresis and energy dissipation. The resultant is an elastic system that can be used reversibly for many times. The underlying mechanism of existence of hysteresis and the physics of snap-back induced elastic instability is unveiled. Our results open an avenue for design and implementation of recoverable energy dissipation devices by harnessing mechanical instability.

New Article in Science Translational Medicine: Application of Mechanical Metamaterials in Medicine

Abstract: We hypothesized that ingested warm fluids could act as triggers for biomedical devices. We investigated heat dissipation throughout the upper gastrointestinal (GI) tract by administering warm (55°C) water to pigs and identified two zones in which thermal actuation could be applied: esophageal (actuation through warm water ingestion) and extra-esophageal (protected from ingestion of warm liquids and actuatable by endoscopically administered warm fluids).
