Abstract

The paper presents the results of a numerical study of the fracture of concrete structures — the protective shell of a nuclear power plant (NPP), under impulse loads. The model of concrete behavior takes into account differences in the limits of compressive and tensile strength, dependence of tensile strengths on the strain rate, plastic properties of concrete, fracture, fragmentation of the shell. Numerical modeling is carried out by finite element method in a three-dimensional statement as part of a phenomenological approach of the mechanics of a continuous medium, using the authors computational software. The dynamics of the fracture of the nuclear power plant protective shell, which has a complex cellular structure and the role of wave processes, is investigated.
