The past decades have been marked by a significant increase in research interest in
nonlinearities in micro-cracked and cracked solids. As a result, a number of different …

The material properties of earth materials often change after the material has been
perturbed (slow dynamics). For example, the seismic velocity of subsurface materials …

A squash ball almost doesn't bounce; a Superball bounces first left then right, seeming to
have a mind of its own. Remarkable and complex elastic behavior isn't confined to sports …

The presence of mesoscopic features and damage in quasi-brittle materials causes
significant second-order and nonlinear effects on the acoustic wave propagation …

Abstract The 1992 magnitude 7.3 Landers earthquake triggered an exceptional number of
additional earthquakes within California and as far north as Yellowstone and Montana …

The nonlinear elastic behaviour of earth materials is an extremely rich topic, one that has
broad implications to earth and materials sciences, including strong ground motion, rock …

Nonlinear elastic wave spectroscopy (NEWS) represents a class of powerful tools which
explore the dynamic nonlinear stress–strain features in the compliant bond system of a …

Experimental properties of a new form of creep dynamics are reported, as manifest in a
variety of sandstones, limestone, and concrete. The creep is a recovery behavior, following …

Repeating earthquakes that rupture approximately the same fault patch and have nearly
identical waveforms are a useful tool for measuring temporal changes in wave propagation …

The rate of chemical weathering has been observed to increase with the rate of physical
erosion in published comparisons of many catchments, but the mechanisms that couple …
