This work deals with the modelling and simulation of curing phenomena in adhesively bonded piezo metal composites which consist of an adhesive layer with integrated piezoelectric module and two surrounding metal sheet layers. In a first step, a general modelling framework is proposed which is able to represent curing phenomena in polymers at finite strains. Based on this formulation, a concretized model is deduced for the simulation of curing in one specific epoxy based adhesive. Here, appropriate material functions are specified and the thermodynamic consistency is proved. Regarding the finite element implementation, a numerical integration scheme and a new approach for the consideration of different initial conditions are provided. Finally, finite element simulations of a newly proposed manufacturing process for the production of bonded piezo metal composite structures are conducted. A deep drawing process of the composite with uncured adhesive layer and the subsequent adhesive curing are investigated.Keywords bonded piezo metal composite · curing adhesive · constitutive model · finite element method

The Presta joining process is the world's leading manufacturing method for assembled camshafts. It is a multi-stage forming process separated in different steps. First, the rolling of the shaft creates a local widening of the intended cam seat. Within the subsequent joining process, the cam is forced onto the widened cam seat to form a tight fit. The two substeps are modelled and simulated using FEM. Within the process large local deformations occur, which requires an appropriate material model. The phenomenological material formulation of finite strain viscoplasticity implemented in the introduced simulation model enables the transfer of the deformation history to a new reference configuration. Hence, at the change of simulation models this feature is applied by passing the material model's internal state variables of the rolling step to the initial FE-mesh of the joining step. This work shows the simulation models of the Presta joining process and gives a detailed insight into the change of the reference configuration.
