Prediction of shear strength of cluster-strengthened aluminum with multi-scale approach describing transition from cutting to bypass of precipitates by dislocations

•Molecular dynamics study of interaction of edge dislocation with 1-4 nm copper clusters in aluminum is carried out.•Main mechanism of overcoming of 1-1.2 nm copper clusters is its cutting by dislocation.•Main mechanism of overcoming of 1.4-4 nm copper clusters is its bypass by Orowan mechanism.•Mod...
