Reyes, Aase Gavina Roberg; Hopperstad, Odd Sture; Lademo, Odd-Geir; Langseth, Magnus (Journal article; Peer reviewed, 2006)The three materials AA7108, AA7003 and AA6060, which can be parts of a typical bumper system in aluminum, were characterized in the present paper. Different tempers of the materials were studied. Through simple material ... -
Modelling and testing of thick aluminium castings under impact loadings
Martinsen, Christoffer (Master thesis, 2018)The main task of this thesis is to evaluate the capacity of a novel modelling approach for aluminium casting to describe the behaviour and failure of an aluminium rim under dynamic loadings. The thesis work will involve ... -
Neural network modelling of mechanical joints for the application in large-scale crash analyses
André, Victor; Costas Pino, Miguel; Langseth, Magnus; Morin, David Didier (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 ... -
A novel tests set-up for validation of connector models subjected to static and impact loadings
Reil, Matthias; Morin, David; Langseth, Magnus; Knoll, Octavian (Peer reviewed; Journal article, 2021)A novel test set-up is presented for validation of hybrid connector models between steel and aluminium components subjected to static and impact loading. The proposed components consisted of two hat profiles in steel and ... -
NUMERICAL SIMULATIONS OF SUBMERGED AND PRESSURISED X65 STEEL PIPES
Kristoffersen, Martin; Casadei, Folco; Børvik, Tore; Langseth, Magnus; Solomos, George; Hopperstad, Odd Sture (Chapter, 2013)While in service, pipelines may from time to time be exposed to impact loads from anchors or trawl gear.
