Abstract:

Exploiting the coupling of different physical properties, e.g. mechanical, electrical, magnetic or optical, smart materials and devices enable various applications as sensors, actuators or data storage devices to name only a few. Besides ferroelectric or ferromagnetic materials, multiferroic composites are within the focus of research. Due to the complex interactions of various physical quantities, an optimal design of smart structures cannot exclusively be based on experiments, but has to be accompanied by numerical simulations. Our constitutive models are formulated on the macroscale treating problems within a continuum mechanics framework. The evolution of inelastic quantities such as switching of unit cells, domain wall motion and microcrack growth, however, is based on processes on the micro- and mesoscales. The Finite-Element method is used to classically solve boundary value problems. A condensed approach has been developed as an efficient alternative, accounting for polycrystalline behavior without any spatial discretization of the grain structure.
