title = "Localizing nonclassical nonlinearity in geological materials with neutron scattering experiments",
abstract = "Deviations from linear elasticity in consolidated rocks have been measured by acoustic methods and by quasistatic application of stress since the early 1900s. We have used elastic neutron scattering to probe a large volume (on a grain-size scale) of a variety of consolidated rocks under dynamic and quasi-static conditions. Differences between macroscopic external strain and average atomic-scale strain were determined. Nonlinear behavior is intimately related to strain magnitudes so the microscopic distribution of strain is important. Our results indicate that a very small volume (< 5%) of the rock is responsible for almost all of the nonlinear response of the bulk rock. We discuss our results and possible future experiments.",
