A large number of models have been proposed in the field of nonlinear elastic wave propagation in damaged solids to validate experimental observations with theoretical predictions. In this contribution, we distinguish between "distributed" and "interface" implementations of nonlinearity, and deduce particular properties for the differing models. For the models of distributed damage, we prove that many of the currently suggested models can be seen as particular cases of the PM-model for specific protocols and parameters. In addition, we illustrate the potentiality of interface models to validate experimental results reported by other research groups.
