Abstract: Abstract Strengthening effects in solid materials depend on different mechanisms, which have been analyzed empirically since very long time. The here presented work shows the investigation on atomistic length scale of precipitate hardening, with detailed look on dislocation obstacle interactions, and grain-boundary-strengthening using Molecular Dynamics to perform numerical simulations on polycrystalline aluminum systems including copper as alloying element. Work hardening effects has been simulated for a notched iron specimen, where periodic loading and compression has been applied. Temperature and density influences are shown for nanoporose iron models.
