Paper Abstract

The behavior of piezo-metal-compounds made of laminar piezo-modules and sheet metal which are formed by various forming processes is simulated. To evaluate the formability of the piezo-modules strains and stresses have to be known. Otherwise finite element models with a discretization in the dimension of the piezomaterial are not suitable for forming simulation concerning the size of the model. The simulation method of unit cells is used to homogenize the material parameters. In order to achieve the real strains and stresses of the piezomaterial the strains/stresses obtained with the homogenous material parameters are superimposed with the phase concentrations from the unit load cases.
