A new method for the assessment of the service reliability of cracked metallic sheet materials from hardness parameters is proposed. It has been shown that the state of the material in the pre-fracture zone of a uniaxially loaded specimen, which is acted upon by a stress that is close to the ultimate strength of the material, corresponds to the state of the damaged material in the crack tip zone before crack initiation.
