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…
Effect of material stiffness on hardness: a computational study based on model potentials
Gerolf Ziegenhain, Herbert M. Urbassek
We investigate the dependence of the hardness of materials on their elastic stiffness. This is possible by constructing a series of model potentials of the Morse type; starting on…
