The elastic energy per unit surface associated to a non‐regular hexagonal network of misfit dislocations lying along a planar interface is expressed analytically for any two anisotropic crystals. The present expression generalizes recent results only valid for a regular hexagonal network formed by dislocations of the same kind of Burgers vectors. It takes into account the specific cut radius associated to each dislocation segment. A numerical application is presented for dislocation network observed at the Cu/Fe interface.
