It is well known that grain boundaries (GBs) have a strong influence on mechanical properties of polycrystalline materials. What is not as well-known is how different GBs interact with dislocations to influence dislocation movement. We present a molecular dynamics study of more than 2 dozen different FCC Ni bicrystals subjected to mechanical loading to induce incident dislocation interactions. The resulting simulations are analyzed to determine properties such as likelihood of transmission and resolved shear stress. The results are analyzed for correlations between the aforementioned properties and a GB’s response to incident dislocations.
