Query: Atomistic survey of grain boundary dislocation interactions in FCC
  Nickel   It is well known that grain boundaries (GBs) have a strong influence on
mechanical properties of polycrystalline materials. Not as well-known is how
different GBs interact with dislocations to influence dislocation movement.
This work presents a molecular dynamics study of 33 different FCC Ni
bicrystals, each subjected to four different strain states to induce incident
dislocation-GB interactions for 132 unique configurations. The resulting
simulations are analyzed to determine properties of the interaction that affect
the likelihood of transmission of the dislocation through the GB in an effort
to better inform mesoscale models of dislocation movement within polycrystals.
It is found that the ability to predict the slip system of a transmitted
dislocation using common geometric criteria is confirmed. Furthermore, machine
learning processes are implemented revealing that geometric properties, such as
the minimum potential residual Burgers vector (RBV) and the disorientation
between the two grains, are stronger indicators of whether or not a dislocation
would transmit than other properties, such as the resolved shear stress.
