Nonlinear Waves in Granular CrystalsPDE 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.
