Abstract
This note deals with plastic behavior, more precisely with the role of possible additional internal variables for the description of observable effects. Based on the experimental experience, models in use are sometimes modified in order to capture new effects which cannot be described by the original version of the model. This modification can be done with additional internal variables. In doing so, one has to take care that the modified models remain thermodynamically consistent. We discuss this issue on the basis of two phenomena in cyclic plasticity. Moreover, we show how the concept of two-mechanism models can be used for the description of interactions between the arising phenomena.
