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…
Strengthening of Al-Cu alloys by Guinier-Preston zones: predictions from atomistic simulations
G. Esteban-Manzanares, B. Bellón, E. Martínez +2
A scale bridging strategy based in molecular statics and molecular dynamics simulations in combination with transition state theory has been developed to determine the flow stress…
Continuous to intermittent flows in growing granular heaps
L. Alonso-Llanes, E. Martínez, A. J. Batista-Leyva +2
If a granular material is poured from above on a horizontal surface between two parallel, vertical plates, a sand heap grows in time. For small piles, the grains flow smoothly down…
An atomistic investigation of the interaction of dislocations with Guinier-Preston zones in Al-Cu alloys
G. Esteban-Manzanares, E. Martínez, J. Segurado +2
The interaction between edge dislocations and Guinier-Preston zones in an Al-Cu alloy was analyzed by means of atomistic simulations. The different thermodynamic functions that det…
Intermittent and continuos flows in granular piles: effects of controlling the feeding height
L. Alonso-Llanes, L. Domínguez-Rubio, E. Martínez +1
Using a specially designed experimental set up, we have studied the so-called continuous to intermittent flow transition in sand piles confined in a Hele-Shaw cell where the deposi…
Intruder penetration into granular matter studied by Lock-in Accelerometry
L. Alonso-Llanes, G. Sánchez-Colina, E. Martínez +3
Understanding the penetration dynamics of intruders in granular beds is relevant not only for fundamental physics, but also for geophysical processes and construction on sediments…
