Behaviour and Modelling of Self-piercing Screw and Self-piercing Rivet Connections: An Experimental and Numerical Investigation
Sønstabø, Johan Kolstø; Holmstrøm, Petter Henrik (Master thesis, 2013)Accurate and reliable models of connections are essential for the design of aluminium parts in cars. Today, there exist a few models customized for self-piercing rivets (SPR), but none for self-piercing screws (SPS). This ... -
Behaviour of Flow-Drilling Screw Connections
Sønstabø, Johan Kolstø; Holmstrøm, Petter Henrik; Morin, David; Langseth, Magnus (Journal article; Peer reviewed, 2014)An experimental study on the behaviour and fracture of flow-drilling screw connections was carried out. Cross test specimens were used to study the deformation and fracture of the connections under different loading modes. ... -
Finite Element Implementation of Fibre-Reinforced Materials Model in Abaqus/Explicit
Vestrum, Ole (Master thesis, 2015)This thesis is concerned with the constitutive modelling of short fibre-reinforced composites in the finite element code Abaqus/Explicit. The model is presented as a generic framework which is based on a two-phase ... -
Macroscopic strength and failure properties of flow-drill screw connections
Sønstabø, Johan Kolstø; Holmstrøm, Petter Henrik; Morin, David; Langseth, Magnus (Journal article; Peer reviewed, 2015)Force–displacement responses and failure behaviour of connections using flow-drill screws to join aluminium sheets were investigated under various quasi-static loading conditions. This included single connector tests under ...
