Abstract: [eng] [cze]
Results of several parallel molecular dynamics crack simulations in bcc iron crystals withup to 128 million atoms are presented. The crack (001)[010] of Griffith type is loaded in Mode I.We observe dislocation emission and twinning near the free sample surfaces and later plasticallyinduced crack initiation. Jsou prezentovány výsledky paralelních simulací metodou molekulární dynamiky krystalech železa, obsahujících až 128 miliónů atomů. Trhlina (001)[010] Griffithova typu je zatížená v módu I. Byla pozorována emise dislokací a dvojčatění u volného povrchu 3D krystalu a později plasticky indukována iniciace trhliny.
