Aluminium plates with geometrical defects subjected to low-velocity impact: Experiments and simulations
Espeseth, Vetle; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2022)In this paper, an experimental and numerical program investigating impact in the low-velocity regime ( m/s) on 1.5 mm thick AA6016 aluminium plates in three different heat treatments (T4/T6/T7) is presented. The tests were ... -
Cack propagation in aluminium alloy plates: experiments, modelling and simulation
Blytt, Aslak Magdalon; Sundt, Sander (Master thesis, 2021)Denne masteroppgaven har studert sprekkpropagering i 1.5mm tykke plater av aluminiumslegeringen AA6016 utsatt for kvasisstatisk- og dynamisk last. Forsøkene har blitt modellert ved bruk av en FEA og en Gurson-Tvergaard-needleman ... -

Ductile failure of aluminium plates: experiments, modelling and simulations
Espeseth, Vetle (Doctoral theses at NTNU;2023:65, Doctoral thesis, 2023)Numerical models and simulations are valuable tools to aid engineers in the design of products and structures and can help reduce the number of costly and time-consuming experiments needed. The modelling of ductile material ... -
Micromechanical modeling of plasticity, damage and fracture in aluminium alloys
Espeseth, Vetle (Master thesis, 2018)A microstructure-based modeling framework for ductile damage and failure has been examined and validated with experiments for an AlMgSi aluminium alloy. A limited number of material tests has been used to calibrate a porous ... -
A numerical study of a size-dependent finite-element based unit cell with primary and secondary voids
Espeseth, Vetle; Morin, David; Faleskog, Jonas; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2021)Aluminium alloys contain various types of intermetallic particles with different sizes, such as constituent particles and dispersoids. The main mechanism of ductile fracture in these materials is assumed to be nucleation ...
