A study of the influence of precipitate free zones on the strain localization and failure of the aluminium alloy AA7075-T651
Fourmeau, Marion; Marioara, Calin Daniel; Børvik, Tore; Benallal, Ahmed; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2015)Age-hardened aluminium alloys have various degrees of precipitate-free zones (PFZs) along grain boundaries (GBs). The PFZs are weak zones and their existence promotes combined transgranular and intergranular fracture, thus ... -
Anisotropic failure modes of high-strength aluminium alloy under various stress states
Fourmeau, Marion; Børvik, Tore; Benallal, A; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2013)The influence of stress state and plastic anisotropy on the fracture behaviour of a rolled AA7075-T651 aluminium plate under quasi-static loading conditions is studied both experimentally and numerically. Material tests ... -
Anisotropic tensile failure of metals by the strain localization theory: An application to a high-strength aluminium alloy
Morin, David; Fourmeau, Marion; Børvik, Tore; Benallal, Ahmed; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2018)This paper investigates the influence of plastic anisotropy on the tensile ductility of a high-strength aluminium alloy. To this end, finite element simulations of smooth and notched tension tests in different material ... -
Characterization and Modelling of the Anisotropic Behaviour of High-Strength Aluminium Alloy
Fourmeau, Marion (Doktoravhandlinger ved NTNU, 1503-8181; 2014:37, Doctoral thesis, 2014)The purpose of the present study is to describe and characterize the anisotropic flow and fracture behaviour of a high-strength aluminium alloy. To this end, thick plates of AA7075-T651 aluminium alloy have been ... -
Micromechanical Modelling of Strain Localization and Fracture in Aluminium
Martinsen, Vegard (Master thesis, 2012)Aluminium is often treated as a homogeneous material. However, when investigated on a microscopic scale, a granular structure is observed. The mechanical properties of the constituents, together with the distribution of ...
