Perforation of welded aluminum components: Microstructure-based modeling and experimental validation
Holmen, Jens Kristian; Børvik, Tore; Myhr, Ole Runar; Fjær, Hallvard Gustav; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2015)Perforation of welded aluminum structures by small-arms bullets is studied both experimentally and numerically in this paper. From the chemical composition, artificial aging history, and welding procedure, the spatial ... -
Perforation of welded aluminum extrusions: Numerical prediction and experimental validation
Holmen, Jens Kristian; Børvik, Tore; Myhr, Ole Runar; Hopperstad, Odd Sture (Chapter, 2015)A purely numerical procedure for predicting the perforation resistance of welded extruded AA6082-T6 aluminum profiles is presented in this study. The numerical work was conducted completely independent of the experimental ... -

Prediction of ductile failure using a phenomenological model calibrated from micromechanical simulations
Holmen, Jens Kristian; Dæhli, Lars Edvard; Hopperstad, Odd Sture; Børvik, Tore (Journal article, 2016)Unit-cell models were in this study utilized to numerically determine the failure locus of a cast and homogenized AA6060 aluminum alloy. Simulations were conducted for moderate and high stress triaxiality ratios, and for ... -
Strength differential effect in age hardened aluminum alloys
Holmen, Jens Kristian; Frodal, Bjørn Håkon; Hopperstad, Odd Sture; Børvik, Tore (Journal article; Peer reviewed, 2017)The strength differential (SD) effect, as reported in literature over the past decades, is a discrepancy between the axial stresses in compression and tension. This study investigates the SD effect in aluminum alloys using ...
