Strongly non-linear continuous model for wave propagation in 2D granular media: derivation and hyperbolicity analysis
In this work, we develop a nonlinear continuum model for wave propagation in two-dimensional granular materials, building on key ideas from Nesterenko's work. Starting from the Hertzian contact law and neglecting contact friction, we derive an effective continuum description through homogenization, assuming spherical,...
