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…
CALPHAD-informed phase-field modeling of grain boundary microchemistry and precipitation in Al-Zn-Mg-Cu alloys
Chuanlai Liu, Alistair Garner, Huan Zhao +4
The grain boundary (GB) microchemistry and precipitation behaviour in high-strength Al-Zn-Mg-Cu alloys has an important influence on their mechanical and electrochemical properties…
On the interaction of precipitates and tensile twins in magnesium alloys
Chuanlai. Liu, Pratheek. Shanthraj, Joseph. Robson +5
Although magnesium alloys deform extensively through shear strains and crystallographic re-orientations associated with the growth of twins, little is known about the strengthening…
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…
