FEM and RBSM Numerical Analyzes of Concrete Wall under Long-term Exposure to Neutron Irradiation
Original language description
In this paper, the mechanical response of a concrete wall to long-term exposure to neutron irradiation is investigated. The radiation effect, represented by neutron flux, is modeled by volumetric swelling of concrete and corresponding degradation of the mechanical parameters of concrete. This effect is investigated using a three-dimensional finite element model of the wall and Rigid-Body-Spring-Model of a strip of a wall that have been created for this purpose. As a result, displacement, isotropic damage, principal compressive and tensile stresses, cracks patterns are obtained. According to the results of this analysis, the analyzed reinforced concrete wall is damaged to such an extent that its load-bearing capacity and shielding performance may be compromised and the strip of the unreinforced concrete wall is completely damaged according to the RBSM analysis.
