In some embodiments, a rotorcraft includes an engine, a rotor hub assembly (32) mechanically coupled to the engine and a plurality of rotor blade assemblies (28) rotatably mounted to the rotor hub assembly (32). Each of the rotor blade assemblies (28) includes a rotor blade having a leading edge and an erosion shield system (56) extending spanwise along the leading edge of the rotor blade. The erosion shield system includes a plurality of erosion shield segments (70-78) positioned adjacent to one another forming joints (80-86) therebetween wherein, the joints (80-86) deform responsive to strain experienced by the rotor blade, thereby isolating the erosion shield segments (70-78) from at least a portion of the strain experienced by the rotor blade.
