As part of the international conference "9th European Congress on Computational Methods in Applied Sciences and Engineering" in Lisbon (03.-07.06.2024), Prof. Dr.-Ing. Jens Wakerfuß successfully presented the current research results of the Institute of Structural Analysis in the field of incorporating nonlinear constraints in the finite element method. During the conference there was a fruitful exchange with other scientists. We are looking forward to the next ECCOMAS in Munich.
