Grain growth competition during melt pool solidification -- Comparing phase-field and cellular automaton models
S. M. Elahi, R. Tavakoli, I. Romero +1
A broad range of computational models have been proposed to predict microstructure development during solidification processing but they have seldom been compared to each other on…
Multiscale simulation of powder-bed fusion processing of metallic alloys
S. M. Elahi, R. Tavakoli, A. K. Boukellal +3
We present a computational framework for the simulations of powder-bed fusion of metallic alloys, which combines: (1) CalPhaD calculations of temperature-dependent alloy properties…
Energy-momentum conserving integration schemes for molecular dynamics
Mark Schiebl, Ignacio Romero
We address the formulation and analysis of energy and momentum conserving time integration schemes in the context of particle dynamics, and in particular atomic systems. The articl…
The rotating rigid body model based on a non-twisting frame
Cristian Guillermo Gebhardt, Ignacio Romero
This work proposes and investigates a new model of the rotating rigid body based on the non-twisting frame. Such a frame consists of three mutually orthogonal unit vectors whose ro…
Structural models based on 3D constitutive laws: variational structure and numerical solution
David Portillo, Bastian Oesterle, Rebecca Thierer +2
In all structural models, the section or fiber response is a relation between the strain measures and the stress resultants. This relation can only be expressed in a simple analyti…
Development of a thermo-mechanically coupled crystal plasticity modeling framework: application to polycrystalline homogenization
Jifeng Li, Ignacio Romero, Javier Segurado
Accurate predictions of thermo-mechanically coupled process in metals can lead to a reduction of cost and an increase of productivity in manufacturing processes such as forming. Fo…
