摘要：

Nonlinear elastic response in rock is established as a robust and representative characteristic in rock rather than a curiosity. We show measurements of this behavior from a variety of experiments on rock taken over many orders of magnitude in strain and frequency. The evidence leads to a pattern of unifying behavior in rock: (1) Nonlinear response in rock is ubiquitous. (2) The response takes place over a large frequency interval (dc to 10(5) kHz at least). (3) The response not only occurs, as is commonly appreciated, at large strains but also at small strains where this behavior and the manifestations of this behavior are commonly disregarded.
