A Monte Carlo code for the collisional evolution of porous aggregates (CPA)
Millan, Emmanuel N.; Planes, María Belén; Urbassek, Herbert M.; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (EDP SCIENCES S A, 2023-03-29)Context. The collisional evolution of submillimeter-sized porous dust aggregates is important in many astrophysical fields.Aims. We have developed a Monte Carlo code to study the processes of collision between mass-asymmetric, ... -
Impact of internal structure on aggregate collisions
Bandyopadhyay, Rahul; Planes, María Belén; Millán, Emmanuel N.; Bringa, Eduardo M. [Centro de Nanotecnología Aplicada, Facultad de Ciencias, Universidad Mayor, Chile]; Urbassek, Herbert M. (Oxford University Press, 2023-09-18)Granular-mechanics simulations are used to study collisions between granular aggregates. We compare the collision outcomes for three different types of aggregate: (i) aggregates constructed by a ballistic particle–cluster ... -
Simulated nanoindentation into single-phase fcc FexNi1-x alloys predicts maximum hardness for equiatomic stoichiometry
Alabd Alhafez, Iyad; Deluigi, Orlando R.; Tramontina, Diego; Ruestes, Carlos J.; Bringa, Eduardo M. [Univ Mayor, Ctr Nanotecnol Aplicada, Chile]; Urbassek, Herbert M. (NATURE PORTFOLIO, 2023-06-16)We investigate by molecular dynamics simulation the mechanical behavior of concentrated alloys under nanoindentation for the special example of single-phase fcc FexNi1-x alloys. The indentation hardness is maximum for the ... -
Spin-lattice-dynamics analysis of magnetic properties of iron under compression
dos Santos, Gonzalo; Meyer, Robert; Tramontina, Diego; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Urbassek, Herbert M. (NATURE PORTFOLIO, 2023-08-31)Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous ...
