Overview

The research group is dedicated to the influence of industrial processing on the microstructure of metals. The investigated processing techniques, such as deep rolling, induction hardening or electrochemical machining, are characterized by different and often combined mechanical, thermal, but also electrochemical loads and lead to different changes in the microstructure. Numerical simulations are nowadays essential for the development and design of industrial products. They significantly reduce the design time and development costs for each component. The aim of the research group is to model different microstructural processes such as dislocation plasticity, phase transformation and anodic resolution. Besides classical continuum mechanical approaches, phase field approaches and variational methods, different numerical methods are also investigated. Examples are robust finite element formulations as well as FE-FFT approaches, which are indispensable for the efficient numerical simulation of the production of industrial components.
