The conceptual success of the [infinitesimal theory of
elasticity and the linear theory of viscosity] is perhaps
the broadest we know in science: in terms of them we
face, “explain”, and in varying amount control, our
daily environment: winds and tides, earthquakes and
sounds, structures and mechanisms, sailing and flying,
heat and light (Truesdell and Noll, 1965).

Elastic deformation
Comparison of displacement field components near an edge
dislocation from phase images of experiments (left column)
and from anisotropic elastic theory (right column). (a) and
(b) displacement component u x parallel to bottom edge of
image. (c) and (d) displacement component u y parallel to left
edge of image. Photograph reproduced from (Hytch et al.,
