One widely observed phenomenon is the yield stress drop after reversal loading, termed as mechanical Bauschinger effect. This effect is attributed to internal back stresses which arise due to accumulated GNDs in the material. The focus of this contribution is to present an explicit modeling approach for the Bauschinger effect by accounting additionally for reverse GND interactions. This effect is found to be very pronounced in gold-polymer nanocomposites. For that reason, cyclic shearing of gold single crystals of two characteristic sample sizes has been performed in the three-dimensional framework. As a demonstrative example, a single slip crystal set-up is considered where the reverse direction is explicitly incorporated.
