Finite Amplitude Waves in Solids: The Hidden Physics
This channel provides information to those interested in architectural acoustics, electroacoustics, psychoacoustics, and 3D audio. The key contents of **Chapter 9: Finite-Amplitude Waves in Solids**, as presented in the provided source, can be summarized within the broader context of nonlinear acoustics as follows: Nonlinear acoustics in solids is distinguished from fluids, where the state of the medium can be defined solely by pressure; because solids possess non-hydrostatic stress states, they must utilize local *'strain'* as a fundamental variable. The nonlinearity occurring in solids stems from two sources: kinematic nonlinearity, which is independent of the medium's properties, and physical nonlinearity, which is the inherent material compositional behavior of the solid.
