Geometrical frustration exists in both metallic glasses and chiral nematic liquid crystals. Applying results from the Landau‐Ginzburg theory of liquid crystals and from polytope models for the amorphous state, a frustrated free‐energy density for metallic glasses is derived. It is expressed in terms of an order parameter that characterizes the bond orientation of neighbouring atoms.
