This unique volume presents an original approach to physical
acoustics with additional emphasis on the most useful surface
acoustic waves on solids. The study is based on foundational work
of Leon Brillouin, and application of the celebrated invariance
theorem of Emmy Noether to an element of volume that is
representative of the wave motion.This approach provides an easy
interpretation of typical wave motions of physical acoustics in
bulk, at surfaces, and across interfaces, in the form of the motion
of associated quasi-particles. This type of motion, Newtonian or
not, depends on the wave motion considered, and on the original
modeling of the continuum that supports it. After a thoughtful
review of Brillouin's fundamental ideas related to radiative
stresses, wave momentum and action, and the necessary reminder on
modern nonlinear continuum thermomechanics, invariance theory and
techniques of asymptotics, a variety of situations and models
illustrates the power and richness of the approach and its strong
potential in applications. Elasticity, piezoelectricity and new
models of continua with nonlinearity, viscosity and some
generalized features (microstructure, weak or strong nonlocality)
or unusual situations (bounding surface with energy, elastic thin
film glued on a surface waveguide), are considered, exhibiting thus
the versatility of the approach.This original book offers an
innovative vision and treatment of the problems of wave propagation
in deformable solids. It opens up new horizons in the theoretical
and applied facets of physical acoustics.
