Minisymposium 03

Computational Modeling of Electromagnetic Functional Materials

Organizers: Bjoern Kiefer and Daniele Rosato

For the last decade, active and functional materials have received much attention both in research and technical application, because they enable the conceptualization and design of efficient, smart, miniaturized and autonomous systems that would not be conceivable with conventional materials. Areas of application have included sensors, actuators, transducers, medical devices, biomimetics (bionics), energy harvesting, health monitoring, self-healing, chemical and bio-hazard sensing. Furthermore, the recent emergence of novel functional material classes and functional composites has given further impetus to this field. The optimal design and successful manufacture of active and multifunctional devices invariably necessitate an accompanying efficient and quantitatively-accurate computational analysis of the products that often possess complex geometries and exhibit complex material response. In this symposium the focus is placed on the modeling of functional materials with electromagneto- mechanical coupling, such as

- piezoelectrics and ferroelectric ceramics
- piezomagnetics and magnetostrictives
- magnetic shape memory alloys
- electroactive/magnetoactive polymers and fluids
- carbon nanotubes
- multifunctional composites

The participants will present recent work on the development of constitutive models for such materials that addresses challenging features of the constitutive behavior related to multi-field coupling, physical and geometrical nonlinearities, anisotropy, dissipation and microstructure evolution. Other important aspects that often place restrictions on the reli- ability and durability of functional materials are related to degradation mechanisms such as fatigue, damage and fracture. In addition to the constitutive model development, the sympo- sium will focus on computational aspects related to algorithmic material model formulations and their implementation into numerical solution techniques for coupled field problems. The symposium aims to bring together young researchers, who have tackled multi-physics problems associated with electomagnetic functional materials. It will provide a forum for the scientists to present their work to an audience of peers, to foster an interdisciplinary exchange of ideas and to discuss state of the art modeling approaches and simulation techniques as well as current developments in this rapidly evolving field of reseach.
