Abstract: In this paper, an attempt is made to describe the structural-statistical aspects of the damage accumulation and fracture of structural steel by means of experimental and numerical micromacromodeling. The new approach of multiscale modeling of structure element fracture based on evolution of microstructure levels is proposed. The lifetime is considered as an ultimate state in a local volume of material, or a critical value of the local damage approaching.
