Simulated nanoindentation into single-phase fcc FexNi1-x alloys predicts maximum hardness for equiatomic stoichiometry
(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
(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 ...
Impact of internal structure on aggregate collisions
(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 ...
A Monte Carlo code for the collisional evolution of porous aggregates (CPA)
(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, ...
