Derivation of the Camassa-Holm equations for elastic waves [PDF]

open access: yes, 2015
In this paper we provide a formal derivation of both the Camassa-Holm equation and the fractional Camassa-Holm equation for the propagation of small-but-finite amplitude long waves in a nonlocally and nonlinearly elastic medium.

Nonlocal elastic compliance for soft solids: Theory, simulations, and experiments [PDF]

open access: yesPhysical Review E, 2008
The nonlocal elastic response function is crucial for understanding many properties of soft solids. This may be obtained by measuring strain-strain autocorrelation functions. We use computer simulations as well as video microscopy data of superparamagnetic colloids to obtain these correlations for two-dimensional triangular solids.

Soft random solids and their heterogeneous elasticity [PDF]

open access: yes, 2009
Spatial heterogeneity in the elastic properties of soft random solids is examined via vulcanization theory. The spatial heterogeneity in the \emph{structure} of soft random solids is a result of the fluctuations locked-in at their synthesis, which also ...

Blow-up and global existence for a general class of nonlocal nonlinear coupled wave equations [PDF]

open access: yes, 2010
We study the initial-value problem for a general class of nonlinear nonlocal coupled wave equations. The problem involves convolution operators with kernel functions whose Fourier transforms are nonnegative.
