The effect of constituent particles on the tear resistance of three 6000-series aluminium alloys
Qvale, Kristin; Thomesen, Susanne; Hopperstad, Odd Sture; Børvik, Tore (Peer reviewed; Journal article, 2022)This paper investigates the tear resistance of three cast and homogenized 6000-series alloys, namely AA6061, AA6063 and AA6110, all in temper T6, by means of Kahn tear tests. Of each alloy one commercial version and one ... -
Energy absorption and failure in aluminium alloys: An experimental and numerical study
Qvale, Kristin (Doctoral theses at NTNU;2022:213, Doctoral thesis, 2022)Aluminium alloys are a preferred group of materials for crash components in the automotive industry, often offering a substantial strength-to-weight ratio and ductility. The R&D process in the automotive industry is ... -
An experimental study on pre-stretched double-chamber 6000-series aluminium profiles subjected to quasi-static and dynamic axial crushing
Qvale, Kristin; Hopperstad, Odd Sture; Reiso, Oddvin; Tundal, Ulf; Marioara, Calin Daniel; Børvik, Tore (Peer reviewed; Journal article, 2020)Automotive crash boxes require a material selection with strength and ductility in a balanced combination. In this work, the behaviour of double-chamber AA6063 and AA6082 aluminium profiles subjected to quasi-static and ... -
Static and dynamic crushing of aluminium profiles
Qvale, Kristin (Master thesis, 2018)In this thesis the static and dynamic axial crushing response of an extruded two-chamber aluminium profile geometry have been studied. The materials tested were two aluminium alloys of the 6000-series, AA6063 and AA6082, ...
