Interaction of highly nonlinear solitary waves with elastic solids containing a spherical void

International Journal of Solids and Structures, 2017
Abstract Numerical calculations are performed to examine the interaction of highly nonlinear solitary waves in one-dimensional granular crystals with elastic solids containing a defect in the form of an embedded spherical void. The calculations are based on a coupled numerical model, combining concepts of discrete and finite elements.

Laser-based excitation of nonlinear solitary waves in a chain of particles [PDF]

, 2011
Highly nonlinear solitary waves (HNSWs) are stress waves that can form and travel in highly nonlinear systems. They are characterized by a constant spatial wavelength and by a tunable propagation speed, dependent on the wave amplitude.
