Behaviour and modelling of flow-drill screw connections
Sønstabø, Johan Kolstø (Doctoral theses at NTNU;2018:73, Doctoral thesis, 2018)This PhD thesis consists of experimental and numerical studies of the behaviour and modelling of flow-drill screw connections. It is comprised of four parts, and each part has been published, or accepted for publication, ... -
Behaviour and modelling of two semi-crystalline polymers over a wide range of rates and temperatures
Schwenke, Einar (Doctoral theses at NTNU;2023:104, Doctoral thesis, 2023)Through this thesis, I seek to explore how to characterise and simulate the strain rate and temperature dependent material behaviour of semi-crystalline polymers. To this end, a cross-linked polyethylene and a polypropylene ... -
Characterisation and modelling of bonded and hybrid assemblies under crash loading
Dameme, Fanny (Doctoral thesis, 2024) -
Deep learning-based analysis to identify fluid-structure interaction effects during the response of blast-loaded plates
Lomazzi, Luca; Morin, David Didier; Cadini, Francesco; Manes, Andrea; Aune, Vegard (Peer reviewed; Journal article, 2023)Blast events within urban areas in recent decades necessitate that protective design is no longer reserved for military installations. Modern civil infrastructure composed of light-weight, flexible materials has introduced ... -
Macroscopic modelling of Flow-Drill Screw connections
Sønstabø, Johan Kolstø; Morin, David Didier; Langseth, Magnus (Journal article; Peer reviewed, 2016)This study focuses on the modelling of Flow-Drill Screw (FDS) connections in large-scale shell analyses. Macroscopic connection models for large-scale crash simulations were assessed for modelling of FDS connections between ... -
Micromechanical modelling of fracture in ductile alloys with applications to high-strength steel
Bergo, Sondre (Doctoral theses at NTNU;2020:313, Doctoral thesis, 2020) -
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 ... -
On the use of a virtual laboratory for aluminium alloys: application to large-scale analyses of extruded profiles
Fernandez Garcia, Marcos (Doctoral theses at NTNU;2022:199, Doctoral thesis, 2022)The global effort of decreasing energy consumption and CO2 emissions has resulted in an important increase in the use of aluminium in the automotive sector. Aluminium (in the form of aluminium alloys) possesses many ... -
Phase-field models for ductile fracture. Stress triaxiality dependent approaches applied to pipeline steel
Sur, Anne-Sophie (Doctoral theses at NTNU;2024:247, Doctoral thesis, 2024)Ductile fracture is associated with plastic deformation and the development of voids in the material, which leads to a gradual fracture evolution. Ductile fracture in metals is of great importance as it can occur in large ... -
A self-consistent void-based rationale for hydrogen embrittlement
Yu, Haiyang; He, Jianying; Morin, David Didier; Ortiz, Michael; Zhang, Zhiliang (Peer reviewed; Journal article, 2025)Solely based on the failure process of metallic materials containing voids, we propose a straightforward rationale for a self-consistent void-based hydrogen embrittlement (CVHE) predictive framework that effectively captures ... -
Surrogate modeling of aluminium extrusion under large deformations
Hansen, Benjamin Aas; Øyhovden, Magnus Øyhovden (Master thesis, 2024)Elementmetodeanalyser (FEA) er et veletablert verktøy for å designe energiabsorberende strukturer under påkjenning. Imidlertid krever gjennomføring av en robusthetsstudie omfattende FEA-simuleringer, som ofte ikke er ... -

Transferability of Temperature Evolution of Dissimilar Wire-Arc Additively Manufactured Components Using Finite Element Simulation through Machine Learning
Fagersand, Håvard Mo; Morin, David Didier; Mathisen, Kjell Magne; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2024)Wire-arc additive manufacturing (WAAM) is a promising industrial production technique. Without optimization, inherent temperature gradients can cause powerful residual stresses and microstructural defects. There is therefore ... -
A Virtual Calibration Strategy and Its Validation for Large-Scale Models of Multi-Sheet Self-Piercing Rivet Connections
André, Victor; Costas, Miguel; Langseth, Magnus; Morin, David Didier (Peer reviewed; Journal article, 2024)
