A variational method for the simulation of hydrogen diffusion in metals
Eva M. Andrés, Ignacio Romero
We present a new method for the approximate solution of the strongly coupled, nonlinear stress-diffusion problem that appears when modeling hydrogen transport in metals. The most s…
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…
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…
