As one of the oldest natural sciences, mechanics occupies a certain
pioneering role in determining the development of exact sciences through
its interaction with mathematics. As a matter of fact, there is hardly
an area in mathematics that hasn't found an application of some form in
mechanics. It is thus almost inevitable that theoretical methods in
mechanics are highly developed and laid out on different levels of
abstraction. With the spread of digital processors this goes as far as
the implementation in commercial computer codes, where the user is
merely con- fronted on the surface with the processes that run in the
background, i. e. mechan- ics as such: in teaching and research, as well
as in the context of industry, me- chanics is much more, and must remain
much more than the mere production of data with the help of a processor.
Mechanics, as it is talked about here, tradition- ally includes a wide
spectrum, ranging from applied mechanics, analytical and technical
mechanics to modeling. and experimental mechanics, as well as technical
realization. It also includes the subdisciplines of rigid body
mechanics, continuum mechanics, or fluid mechanics, to mention only a
few. One of the fundamental and most important concepts used by nearly
all natural sciences is the concept of linearization, which assumes the
differentiability of mappings. As a matter of fact, all of classical
mechanics is based on the avail- ability of this quality.
