Award for Lennart Stöttelder

The Faculty of Civil and Environmental Engineering has nominated Lennart Stöttelder for the 2026 RUB Student Award in recognition of his outstanding thesis, 'Computationally Simple and Efficient Locking Alleviation in Isogeometric Thin Shells.' This prestigious prize is conferred annually by the Rectorate of Ruhr University Bochum.

The master thesis presents an improved version of the hybrid membrane-bending interpolation method of Sauer et al. (2024) for isogeometric thin shells. The proposed modifications reduce computational cost through reduced integration and a single-element formulation while preserving the locking-free behavior and accuracy of the original method. Extensive L2-error convergence studies demonstrate the superior performance of the proposed B2M1-formulation compared to classical isogeometric shell formulations.

We congratulate Lennart on his award.
