Concrete is modeled using a meso-mechanical approach in which aggregates and mortar are represented explicitly. Both continuum phases are considered to behave elastically, while nucleation, coalescence and propagation of cracks are modeled using the cohesive-element approach.Finite element analysisTensile propertiesMicromechanicsConcreteDependent Cohesive ModelBrittle MaterialsStrain-RateCrack-PropagationUniaxial TensionLattice ModelDamageEnergyStrengthImpactInfluence of the meso-structure in dynamic fracture simulation of concrete under tensile loadingtext::conference output::conference presentation
