Knut Andreas has a background from Chalmers University of Technology in computational and experimental finite strain plasticity, with particular emphasis on anisotropy evolution. Currently, he is working with scientific machine learning for plasticity modeling and computational and experimental analysis of freezing of reinforced concrete. The latter is related to the GRK activities and involves analyzing the phase transformation process in our micro-CT at the Institute of Applied Mechanics. Further work will also consider the corrosion of reinforcements. Understanding these complex phenomena requires discussions and collaborations with other domain-specific experts, to which end the GRK is a perfect fit.
