Nonlinear Waves in Granular Crystals

PDE and Applied Math Seminar

Speaker: Mason Porter, Stanford University
Location: 2112 MSB
Start time: Thu, Feb 28 2013, 3:10PM

I will discuss recent investigations of highly nonlinear solitary waves in granular chains using numerical computations, analytical calculations, and experiments. I will provide an introduction to both solitary waves and granular chains, and then I will focus on the dynamics of intrinsic localized modes in diatomic chains and chains with defects. I will also briefly discuss the propagation of waves in disordered chains and present an interesting order-disorder transition that is ripe for further study.
