Dislocation emission from the crack tip in bcc iron
 Rosecký, Zdeněk ; Machová, Anna ; Cejp, J.
Atomistic simulations under plane strain conditions by molecular dynamic technique in bcc iron show that microcracks with orientation (-110)[110] can emitt complete edge dislocations in the slip systems <111>{112}. Motion of the dislocations away from

Influence of temperature on residual stress and damage in bcc iron containing Cu nanoparticles
 Machová, Anna
The paper is devoted to 3D molecular dynamic simulations in bcc iron containing coherent copper nano-particles and to analysis of thermal effects on residual stress and damage in the Fe-Cu system.

Simulations of brittle-ductile behavior of crucks in alfha iron
 Rosecký, Zdeněk ; Machová, Anna
Atomistic simulations in bcc iron under plane strain show that cracks with orientation (-110) [110] emitt dislocations which causes crack blunting and crack stability near the critical Griffith stress.
Detailed record
Simulations of temperature and thermal expansion in bcc iron by molecular dynamics, comparison with experiments
 Machová, Anna
The contribution presents some results from atomistic simulations of thermal expansion in bcc iron.the atomistic results agree well with experimental values for thermal expansion in iron.
Detailed record
Transonic twinning from the crack tip /Z 1281/00/
 Červ, Jan ; Landa, Michal ; Machová, Anna
Molecular dynamic simulations in bcc iron show that transonic twinning from the crack tip is possible at low temperatures. The speed of twin expansion is larger than the velocity of shear stress waves along the slip systems <111>{112} in a perfect bcc iron crystal.
