Mechanical memories in solids, from disorder to design
Solids are rigid, which means that when left undisturbed, their structures
are nearly static. It follows that these structures depend on history -- but it
is surprising that they hold readable memories of past events. Here we review
the research that has recently flourished around mechanical memory formation,
beginning with amorphous solids' various memories of deformation and mesoscopic
models based on particle rearrangements. We describe how these concepts apply
to a much wider range of solids and glassy matter -- and how they are a bridge
to memory and physical computing in mechanical metamaterials. An understanding
of memory in all these solids can potentially be the basis for designing or
training functionality into materials. Just as important is memory's value for
understanding matter whenever it is complex, frustrated, and out of
equilibrium.
