Multiscale modelling of precipitation hardening in Al-Cu alloys: dislocation dynamics simulations and experimental validation
R. Santos-Güemes, B. Bellón, G. Esteban-Manzanares +3
The mechanisms of dislocation/precipitate interactions were analyzed in an Al-Cu alloy containing a homogeneous dispersion of precipitates by means of discrete dislocation dyn…
Effect of Al content on the critical resolved shear stress for twin nucleation and growth in Mg alloys
Jingya Wang, Jon M. Molina-Aldareguía, Javier LLorca
The effect of Al atoms in solid solution on the critical resolved shear stress for twin nucleation and growth was analyzed by means of the combination of diffusion couples with com…
Interactions between basal dislocations and precipitates in Mg-4Zn alloy: mechanisms and strengthening
R. Alizadeh, J. LLorca
The mechanisms of dislocation/precipitate interaction as well as the critical resolved shear stress were determined as a function of temperature in a Mg-4 wt. % Zn alloy by means o…
A criterion for slip transfer at grain boundaries in Al
R. Alizadeh, M. Peña-Ortega, T. R. Bieler +1
The slip transfer phenomenon was studied at the grain boundaries of pure Aluminum by means of slip trace analysis. Either slip transfer or blocked slip was analyzed in more than 25…
High fidelity simulation of the mechanical behavior of closed-cell polyurethane foams
M. Marvi-Mashhadi, C. S. Lopes, J. LLorca
The mechanical behavior of closed-cell foams in compression is analyzed by means of the finite element simulation of a representative volume element of the microstructure. The digi…
Influence of the stress state on the cross-slip free energy barrier in Al: an atomistic investigation
G. Esteban-Manzanares, R. Santos-Güemes, . Papadimitriou +2
The influence of the stress state on the cross-slip rate in Al was analyzed by means of molecular dynamics simulations and transition state theory. The activation energy barrier in…
