Gustav Grimstad

Gustav Grimstad is a Professor at the Norwegian University of Science and Technology (NTNU), affiliated with the Department of Civil and Environmental Engineering under the Faculty of Engineering. His research focuses on geomechanics, geotechnics, and soil modeling, with particular emphasis on creep behavior in soft clays, landslide mechanics, and frozen soil dynamics. He has developed models like the NGI-ADP for commercial use in geotechnical software.

Key research areas include progressive failure in quick clays, submarine landslide mechanisms, and the degradation of permafrost under climate change. His work integrates computational methods such as MPM-CFD and hyperplastic constitutive models. Grimstad collaborates on projects addressing infrastructure resilience in sensitive geotechnical environments, including offshore wind turbine foundations and peat embankment settlements.

Publications span topics from frost heave modeling to seismic-induced submarine landslides, emphasizing numerical methods and validation against experimental data. His contributions include advancing understanding of strain localization and mesh independence in sensitive clays, as well as improving design practices for flexible culverts and stabilized quick clay.
