Mesoscopic modelling of concrete under impact
Abstract
We present a mesoscopic model for the analysis of tensile failure of concrete under impact loading. Rate dependency is incorporated through viscosity terms in the constitutive formulation. The model is applied to mesoscopic analyses of three-phase mesoscopic descriptions of concrete consisting of elastic aggregates, inelastic bulk material and interfacial transition zones (ITZs). The tensile strength of the ITZ influences the global strength and the shape of the final failure zone. Different aggregate distributions affect the diffuse failure pattern but the change of the overall strength is less significant. The numerical responses are compared with experimental results from a gravity driven Split Hopkinson bar test setup.
