Emergent friction in two-dimensional Frenkel-Kontorova models
Norell, Jesper; Fasolino, Annalisa; de Wijn, Astrid Silvia (Journal article, 2016)Simple models for friction are typically one-dimensional, but real interfaces are two-dimensional. We investigate the effects of the second dimension on static and dynamic friction by using the Frenkel-Kontorova (FK) model. ... -
Multi-scale study of hydrogen-assisted cracking in nickel-based superalloys
Lu, Xu (Doctoral theses at NTNU;2020:91, Doctoral thesis, 2020)Precipitation-hardened nickel-based superalloys are widely used for subsea oil and gas industries. However, they are susceptible to hydrogen embrittlement (HE) when they are used in the hydrogenated environment. There are ...
