Temperature-dependent magnetism in Fe foams via spin-lattice dynamics
Robert Meyer, Felipe Valencia, Gonzalo dos Santos +3
Spin-lattice dynamics is used to study the magnetic properties of Fe foams. The temperature dependence of the magnetization in foams is determined as a function of the fraction of…
Morphology of graphene flakes in Ni-graphene nanocomposites and its influence on hardness: an atomistic study
Vardan Hoviki Vardanyan, Herbert M. Urbassek
The effect of graphene flakes on the strength of Ni-graphene composites is investigated using molecular dynamics simulation. Rather than introducing flakes as flat structures into…
Structure and size of the plastic zone formed during nanoindentation of a metallic glass
Karina E. Avila, Stefan Küchemann, Herbert M. Urbassek
Using molecular dynamics simulation, we study the plastic zone created during nanoindentation of a large CuZr glass system. The plastic zone consists of a core region, in which vir…
Nanoscratching of metallic glasses -- An atomistic study
Karina E. Avila, Stefan Küchemann, Iyad Alabd Alhafez +1
Tribological properties of materials play an important role in engineering applications. Up to now, a number of experimental studies have identified correlations between tribologic…
Nanoscratching of iron: a novel approach to characterize dislocation microstructures
Nina Gunkelmann, Iyad Alabd Alhafez, Dominik Steinberger +2
A new approach for characterizing the dislocation microstructure obtained from atomistic simulations is introduced, which relies on converting properties of discrete lines to conti…
Contact angle of sessile drops in Lennard-Jones systems
Stefan Becker, Herbert M. Urbassek, Martin Horsch +1
Molecular dynamics simulation is used for studying the contact angle of nanoscale sessile drops on a planar solid wall in a system interacting via the truncated and shifted Lennard…
Influence of crystal anisotropy on elastic deformation and onset of plasticity in nanoindentation -- a simulational study
Gerolf Ziegenhain, Herbert M. Urbassek, Alexander Hartmaier
Using molecular-dynamics simulation and finite-element modelling, we simulate nanoindentation into the three principal surfaces -- the (100), (110) and (111) surface -- of Cu and A…
Cluster-induced crater formation
Christian Anders, Gerolf Ziegenhain, Steffen Zimmermann +1
Using molecular-dynamics simulation, we study the crater volumes induced by energetic impacts ( km/s) of projectiles containing up to N=1000 atoms. We find that for Lenn…
Pair vs many-body potentials: influence on elastic and plastic behavior in nanoindentation
Gerolf Ziegenhain, Alexander Hartmaier, Herbert M. Urbassek
Molecular-dynamics simulation can give atomistic information on the processes occurring in nanoindentation experiments. In particular, the nucleation of dislocation loops, their gr…
