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…
Development and comparison of spectral algorithms for numerical modeling of the quasi-static mechanical behavior of inhomogeneous materials
M. Khorrami, J. R. Mianroodi, P. Shanthraj +1
In the current work, a number of algorithms are developed and compared for the numerical solution of periodic (quasi-static) linear elastic mechanical boundary-value problems (BVPs…
Multi-component chemo-mechanics based on transport relations for the chemical potential
Pratheek Shanthraj, Chuanlai Liu, Amirhassan Akbarian +2
A chemo-mechanical model for a finite-strain elasto-viscoplastic material containing multiple chemical components is formulated and an efficient numerical implementation is develop…
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…
