PD Dr.-Ing. habil. Tobias Kaiser has been a private lecturer in Solid Mechanics at the Institute of Mechanics at TU Dortmund since November 2023. In the same year, he completed his habilitation in Solid Mechanics with a thesis on “Multiscale Multiphysics Material Modeling.” Prior to that, he received his doctorate from TU Dortmund in 2019 with a dissertation entitled “Computational Modeling of Non-Simple and Anisotropic Materials.” His research interests include gradient and crystal plasticity, damage and fracture mechanics, anisotropic materials, electro-mechanical coupling, and multiscale material modeling.
The importance of different length scales in materials science is well-recognized and subject of intense interdisciplinary research efforts. In these developments, multiscale modelling approaches take a key role as these enable the prediction of the effective material response based on detailed microstructure representations. Against this background, we focus on a scale-bridging understanding of macroscale material interfaces and on the influence of microscale interfaces on the effective properties of continua. We make use of classic energy-based homogenisation approaches, extend these to material interfaces, and demonstrate the usefulness of the proposed generalised multiscale formulations by comparison with experimental data.
