Phase-Field Modeling of Coupled Brittle-Ductile Fracture in Aluminum Alloys
Samad Vakili, Pratheek Shanthraj, Franz Roters +2
Fracture in aluminum alloys with precipitates involves at least two mechanisms, namely, ductile fracture of the aluminum-rich matrix and brittle fracture of the precipitates. In th…
Quantification of 3D spatial correlations between state variables and distances to the grain boundary network in full-field crystal plasticity spectral method simulations
Markus Kühbach, Franz Roters
Deformation microstructure heterogeneities play a pivotal role during dislocation patterning and interface network restructuring. Thus, they affect indirectly how an alloy recrysta…
Application-oriented strain-hardening engineering of high-manganese steels
Christian Haase, Franz Roters, Angela Quadfasel
The outstanding mechanical properties of high-manganese steels (HMnS) are a result of their high strain-hardenability. That is facilitated by strong suppression of dynamic recovery…
Understanding the mechanisms of electroplasticity from a crystal plasticity perspective
Arka Lahiri, Pratheek Shanthraj, Franz Roters
Electroplasticity is defined as the reduction in flow stress of a material undergoing deformation on passing an electrical pulse through it. The lowering of flow stress during elec…
Brittle to Quasi-Brittle Transition and Crack Initiation Precursors in Disordered Crystals
S. Papanikolaou, J. Thibault, C. Woodward +2
Crack initiation emerges due to a combination of elasticity, plasticity, and disorder, and it is heavily dependent on the material's microstructural details. In this paper, we inve…
