Nature-inspired Entwined Coiled Carbon Mechanical Metamaterials: Molecular Dynamics Simulations
(Journal article, 2018)Entwining-induced robust natural biosystems show superior mechanical performances over the counterpart. However, the role played by topological entwinement on the mechanical properties of artificial nanohelixes remains ... -
Nedbryting av sprøytebetong i E39 Hopstunnelen og Nesttuntunnelen
(Master thesis, 2015)Hopstunnelen og Nesttuntunnelen på E39 like sør for Bergen sentrum, er 2 tunnelar som opna for trafikk i 2002. Tunnelane er landtunnelar med to-vegs trafikk i 1 løp. Dei går gjennom berg av gneis og skifer og er kledd med ... -
Network arch timber bridges with light timber deck on transverse crossbeams
(Doctoral theses at NTNU;2017:318, Doctoral thesis, 2017)In modern bridge engineering, timber is more and more often considered as a choice for structural material. The advantages are evident: timber is environmentally friendly, easy to shape, thus it can meet various architectural ... -
Neural network modelling of mechanical joints for the application in large-scale crash analyses
(Peer reviewed; Journal article, 2023)This paper presents an artificial neural network (NN) modelling approach to represent a connector model in large-scale finite element explicit crash simulations. The NN model was established to describe the local ... -
New Concept for Durable Concrete Bridges
