Metal Fatigue


The spontaneous formation of dislocation patterns is one of the most striking features of ductile crystalline solids subjected to cyclic loading at the micro scale. The physics of Persistent Slip Band (PSB) formation in fcc metals is explored through Dislocation Dynamics (DD) computer simulations. The interaction between interstitial- and vacancy-type prismatic dipolar loops and glide screw dislocations is explored.
