Hard-magnetic soft materials are a class of magnetically responsive composites obtained by
embedding hard-magnetic particles into a soft polymeric matrix. They have found …

Instabilities in solids and structures are ubiquitous across all length and time scales, and
engineering design principles have commonly aimed at preventing instability. However …

We experimentally, numerically, and analytically investigate transition waves in a
mechanical metamaterial comprising a chain of tristable elements. Transition waves can be …

The ability for materials to adapt their shape and mechanical properties to the local
environment is useful in a variety of applications, from soft robots to deployable structures. In …

Solid–solid phase transformations can affect energy transduction and change material
properties (eg, superelasticity in shape memory alloys and soft elasticity in liquid crystal …

Pattern switching (or transformation) widely exists in the activities of various creatures and
plays an important role in designing adaptive structures in modern materials. Utilizing the …

In this work, we show through the use of experiments validated by computer simulations the
potential of a novel accordion-like magneto-mechanical metamaterial to change its linear …

Metamaterials have thrived in recent years, with negative stiffness mechanical
metamaterials emerging as an essential branch. Extensive research in the past decade has …

This work provides a rigorous analysis of the effective response, ie, average magnetization
and magnetostriction, of magnetoelastic composites that are subjected to overall magnetic …
