cze Abstract:
[cze][eng] Atomární simulace v železe alfa při rovinné deformaci ukazují, že trhliny s orientací (-110) [110] emitují dislokace což způsobuje otupení trhliny a její stabilitu blízko kritického Griffitsova napětí.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.
