## Nonlinear Continuum Mechanics, Electrodynamics and Ether Theories

####
All attempts of describing fundamental physics with
continuum mechanics in the 19th century have been
falsified by the famous experiments by Michelson and Morley
that seem to have disproved the concept of an aether.
The aether theorists however
never thought of particles as being topological defects
creating a displacement field - which is not astonishing,
since the first examples of such defects, dislocations
in solids, were discovered in 1934
by Taylor, almost 30 years after aether theories
had disappeared from the stage of theoretical physics.
In view of the results of Frank (1949) and others, however, one
must say that the wrong concept was not describing spacetime
as an elastic continuum but a wrong or missing picture of
particles moving in it
The hypothesis that elementary particles
could be topological defects in an elastic continuum is
backed by interesting results of modern nonlinear
continuum mechanics (Truesdell 1960, Beatty 1987, Hayes 2000).
This is discussed in the papers
