Mechanics of Materials

The emphasis of the group in the field of mechanics of materials is on multiphysical and multiscale modeling.

In the first place multifunctional materials are considered. The investigated coupled fields cover in particular mechanical, thermal, and electric fields. Methods employed include phenomenological constitutive modeling, micro mechanics, finite element methods, discrete element method, and phase field modeling. Number one priority is always on a sound physical modeling of the phenomena under consideration.

Special experimental methods have been developed to investigate the coupled electromechanical hysteresis properties of ferroelectrics.

Ferroelectrics are a class of materials that exhibit both a spontaneous electric polarization and strain, which can be switched by mechanical or electrical loading. Therefore, they are perfectly suited for applications like actuators and sensors. Thermodynamically motivated phase field modeling is done to predict the evolution of ferroelectric domains on the mesoscale as well as phenomenological modeling on the macroscale [more....]

Granular materials consist of an assembly of discrete solid particles, which behave collectively. Materials of this type have been considered as functional materials for tritium breeder and neutron multiplier in fusion blankets. Considering the microstructure, we use both phenomenological (FEM) and discrete element methods (DEM) to model the thermomechanical response

Li-ion Batteries are promising candidates for storage of electrical energy for high power and high energy applications. Work here deals with micromechanical and phase field modeling of the coupling between diffusion processes and mechanical stresses in electrode particles

Thermoelectric materials are defined by the interaction of thermal and electric properties. Of particular importance is the transfer from one energy state into the other. Reduction of thermal conductivity by structuring at the nanoscale in multilayer systems leads to the improvement of the Seebeck-coefficient [more....]
