A computational study on efficient yield surface calibrations using a crystal plasticity spectral solver
Imani Aria, Arash; Manik, Tomas; Holmedal, Bjørn; Marthinsen, Knut (Journal article, 2023)A computational framework is presented, capable of calculating virtual loads using the spectral solver in the DAMASK software for crystal plasticity simulations in desired stress directions. Calculations are used for the ... -
Crystal-plasticity modelling of the yield surfaces and anelasticity in the elastoplastic transition of metals
Imani Aria, Arash; Holmedal, Bjørn; Manik, Tomas; Marthinsen, Knut (Journal article; Peer reviewed, 2024)The paper presents a full-field crystal-plasticity computational investigation of 10 με small-strain-offset yield surfaces with pointed vertexes that are seen in the elastoplastic transition of pre-strained polycrystal ... -
Deformation Texture Evolution in Flat Profile AlMgSi Extrusions: Experiments, FEM, and Crystal Plasticity Modeling
Manik, Tomas; Marthinsen, Knut; Zhang, Kai; Imani Aria, Arash; Holmedal, Bjørn (Peer reviewed; Journal article, 2021)In the present work, the deformation textures during flat profile extrusion from round billets of an AA6063 and an AA6082 aluminium alloy have been numerically modeled by coupling FEM flow simulations and crystal plasticity ... -
A Full-Field Crystal Plasticity Study on the Bauschinger Effect Caused by Non-Shearable Particles and Voids in Aluminium Single Crystals
Imani Aria, Arash; Holmedal, Bjørn; Manik, Tomas; Marthinsen, Knut (Journal article; Peer reviewed, 2024)In the present work, the goal is to use two-scale simulations to be incorporated into the full-field open software DAMASK version 2.0.3 crystal plasticity framework, in relation to the Bauschinger effect caused by the ...
