Acoustic emission sources from fast dislocation motion
Hora, Petr ; Machová, Anna ; Červ, Jan ; Uhnáková, Alena
Acoustic emission from the fast dislocations emitted from an edge crack in 3D bcc iron crystal is studied via atomistic simulations by molecular dynamics technique. Acoustic emission patterns arising from the fast dislocation motion in molecular dynamics are visualized via the local kinetic energies of individual atoms and further modeled as a moving source of the stress waves in the anisotropic continuum.
Víceúrovňová studie deformačních procesů v monokrystalech Fe-3%Si
Prahl, Jakub ; Machová, Anna ; Landa, Michal ; Libert, M. ; Rey, C. ; Haušild, P. ; Karlík, M.
Two different approaches were successfully used to simulate deformation processes in the vicinity of edge notches in bcc iron. As well as in experiments performed on Fe-3%Si single crystals, the strong dependence of plastic behavior on boundary conditions was found by modeling.
Wave propagation simulations by molecular dynamics methods
Pelikán, Vladimír ; Hora, Petr ; Machová, Anna
We present large-scale molecular dynamic simulations of wave propagationin alfa-iron based on an N-body potential model which gives a good descriptionof anisotropic elasticity. We show that the basic behavior of the simulations is inagreement with the predictions of continuum models.
