Abstract
This talk is an introduction to nonlinear acoustic processes in complex solids such as cracked metals, damaged composites or concrete, and granular media. These materials, belong to the same class of complex solids often referred to as mesoscopic solids, and share a number of similar nonlinear acoustic behaviors originating mainly from the presence of internal solid contacts. The specific nonlinear acoustic signatures and processes will be described (slow dynamics, memory, contact acoustic nonlinearity, i.e. nonclassical nonlinearities) through several examples, and an overview of the main modeling tools will be provided. Finally, the current trends and several applications of such nonclassical nonlinear processes (nondestructive testing and characterization, wave control, etc.) will be given.
