Special Topics in Solid Mechanics
Units to be arranged

first, second, third terms
Subject matter changes depending upon staff and student interest. (1) Stress Waves in Solids. 9 units (3-0-6); second term. Stress waves will be introduced by considering plane waves which allow the principal features of stress wave propagation to be explored without introducing the geometric complexities of waves in 3D. Formulation will include elastic materials and dissipative materials that are modeled as viscoelastic or viscoplastic. For elastic materials, we will consider waves in unbounded anisotropic media, refraction at plane boundaries, surface waves, wave guides, phase velocity and group velocity, waves in periodic media, energy transport, and diffraction. For dissipative materials, we will consider frequency- dependent attenuation, elastic precursor decay, and nonlinear waves in 1D. Examples, and opportunities to explore more advanced topics, will be chosen to try to respond to student interests.
