A numerical study of beam-to-column joints subjected to impact

Grimsmo, Erik Løhre; Clausen, Arild Holm; Aalberg, Arne; Langseth, Magnus (Journal article; Peer reviewed, 2016)

Limited documentation is concerned with the behaviour of steel joints subjected to severe impulsive loading originating from incidents such as explosions or impact. In this paper, finite element simulations are used to ...

A shock tube facility to generate blast loading on structures

Aune, Vegard; Fagerholt, Egil; Langseth, Magnus; Børvik, Tore (Journal article; Peer reviewed, 2016)

This study evaluates the performance of a new shock tube facility used to produce blast loading in controlled laboratory environments. The facility was found to generate a planar shock wave over the tube cross section by ...

A Shock Tube Used to Study the Dynamic Response of Blast-Loaded Plates

Aune, Vegard; Casadei, Folco; Valsamos, Georgios; Langseth, Magnus; Børvik, Tore (Journal article; Peer reviewed, 2018)

This study aims to a better understanding of the performance of a shock tube used to produce blast loading in controlled laboratory environments. Special focus is placed on the influence of the diaphragm failure process ...

A through-thickness damage regularisation scheme for shell elements subjected to severe bending and membrane deformations

Costas Pino, Miguel; Morin, David; Hopperstad, Odd Sture; Børvik, Tore; Langseth, Magnus (Journal article; Peer reviewed, 2018)

This research work proposes and validates a damage regularisation model for shell elements used in large-scale simulations. The model evaluates the ratio of bending to membrane loading in the elements based on the ...

Aluminium Self-Piercing Rivet's Failure: Testing and Numerical Analyses

Hoang, Nguyen-Hieu; Langseth, Magnus (Journal article; Peer reviewed, 2014)

In the present study, the behaviour of aluminium rivets in alloy AA7278-T6 during the riveting process when used to join two aluminium plates was investigated experimentally and numerically. It was observed by Hoang et al. ...

Aluminum foam-filled extrusions subjected to oblique loading: experimental and numerical study

Reyes, Aase Gavina Roberg; Hopperstad, Odd Sture; Langseth, Magnus (Journal article; Peer reviewed, 2004)

The behavior of empty and foam-filled square thin-walled aluminum columns in alloy AA6060 subjected to quasi-static oblique loading was examined. Previous studies have shown that by introducing a load angle, the energy ...

An experimental study of static and dynamic behaviour of bolted end-plate joints of steel

Grimsmo, Erik Løhre; Clausen, Arild Holm; Langseth, Magnus; Aalberg, Arne (Journal article; Peer reviewed, 2015)

Many actions, such as accidental or malicious explosions, may impose high loading rates to structural frames. To enhance the knowledge of the behaviour of joints subjected to severe impulsive loading, a double-sided ...

Assessment of yield and fracture criteria using shear and bending tests

Reyes, Aase Gavina Roberg; Eriksson, Magnus; Lademo, Odd-Geir; Hopperstad, Odd Sture; Langseth, Magnus (Journal article; Peer reviewed, 2009)

This article deals with the calibration of a fracture criterion that has been implemented in a material model in LS-DYNA. The failure process in thin-walled metallic materials is complex and often due to interaction between ...

Axial crushing of aluminum extrusions filled with PET foam and GFRP. An experimental investigation

Costas, Miguel; Morin, David; Langseth, Magnus; Romera, Luis Esteban; Díaz, Jacobo M. (Journal article, 2016)

This research work investigated the axial crushing behavior of a circular aluminum extrusion in alloy AA6063-T5 internally reinforced with a glass–fiber structure and filled with polymeric foam. The components were ...

Behaviour and failure of aluminium extrusions under bending and stretching

Lund, Tobias (Master thesis, 2018)

Current and future strategic challenges in the construction industry require safe and lightweight structures to achieve a good strength to weight ratio. Authentic material combinations together with numerical simulations ...

Behaviour and modelling of cast aluminium rims subjected to impact loading

Kittilsen, Eirik Thanem; Swanberg, Emil (Master thesis, 2017)

The aim of this master s project is to evaluate the capabilities of the SIMLab Metal models (cast aluminium model) to predict the response including failure of a given rim subjected to impact loading conditions. The modelling ...

Behaviour and Modelling of Flexible Structures Subjected to Blast Loading

Aune, Vegard (Doctoral theses at NTNU;2017:101, Doctoral thesis, 2017)

The last two decades have seen a significant increase in the research activity on blast-loaded structures. This is to a large extent related to the increased threat of deliberate use of high explosives against civilian ...
