(II) Introduction to continuum mechanics and elastic wave propagation with an emphasis on principles and results important in seismology and earth sciences in general. Topics include a brief overview of elementary mechanics, stress and strain, Hooke’s law, notions of geostatic pressure and isostacy, fluid flow and Navier-Stokes equation. Basic discussion of the wave equation for elastic media, plane wave and their reflection/transmission at interfaces. Prerequisites: MATH213, PHGN200. 3 hours lecture; 3 semester hours.
