Incorporating precipitation-related effects on plastic anisotropy of age-hardenable aluminium alloys into crystal plasticity constitutive models

Autor: Wessel, Alexander, Perdahcıoğlu, Emin Semih, Boogaard, Antonius Henricus van den, Butz, Alexander, Volk, Wolfram

Crystal plasticity finite element simulations are frequently employed to predict the plastic anisotropy of polycrystalline metals based on their crystallographic texture. However, precipitation in age-hardenable aluminium alloys is known to affect th

Machine learning-based sampling of virtual experiments within the full stress state

Autor: Wessel, Alexander, Morand, Lukas, Butz, Alexander, Helm, Dirk, Volk, Wolfram

This paper presents a new machine learning-based approach to investigate anisotropic yield surfaces of sheet metals by means of virtual experiments. The new sampling approach is based on the machine learning technique known as active learning, which
