Aeronautical structures such as jet engines shafts, wheels, brakes or landing gears are made of Ultra High Strenth Steels (UHSS). Due to their hard martensitic matrix reinforced with second phase particles, such steels exhibit extreme mechanical resistance, their yield strength can overcome 1900 MPa and their ultimate tensile strength can reach 2300 MPa. Such materials are selected based on their tensile properties, however strain at necking (maximum load) is only few percent. Conventional certified design methods assume that failure occurs when a given point of the structure reaches this strain. Regarding UHSS this approach is very conservative; those materials are still able to bear large strains after necking start. The aim of this work ...
