The simulation of a wave propagation in a bcc iron crystal with a crack
We present a large-scale molecular dynamic simulations of a wave propagation in a bcc iron based on a N-body potential model which gives a good description of an anisotropic elasticity. A crack is embedded in a bcc iron...

Ductile?brittle behavior at blunted cavities in 3D iron crystals uncovered and covered by copper atoms
cavity in comparison with the blunted cavity in pure bcc iron. We show that the dislocation emission is easier in the Fe?Cu system in comparison with pure bcc iron in pure bcc iron....

Slip processes and fracture in iron crystals
We present resuts of 3D molecular dynamic simulations in bcc single crystals with embedded cracks of different orientations. The craks are loaded in tension mode I. Our contribution shows that the temperature, crack orientation and various s...

Growth of a brittle crack (001) in 3D bcc iron crystal with a Cu nano-particle
Paper deals with crack extension under mode I in a 3D crystal of bcc iron with a small Cu inhomogeneity in front of the crack via 3D atomistic simulations by molecular dynamics. The results show that after fast Cu penetration crack ...

Britte-ductile behavior in bcc iron containing copper nano-particles.
Brittle-ductile behavior in bcc iron containing copper nano-precipitates is modeled by means of 2D (plane strain) molecular dynamic simulations. Possible sources of the embrittlement caused by copper particles are discussed....
