On introduction of spatial material randomness into lattice-particle model of concrete fracture

Original language description

We present a numerical study on virtual concrete beams with shallow midspan notches loaded in three-point bending. We document how spatial randomness of material parameters allows a crack to initiate outside the shallow notch. The effect of notch depth and fluctuation rate of material parameters is shown. We use a discrete meso-level model to simulate material behavior. An approach that introduces material spatial randomness into the discrete mechanical model for concrete fracture through an autocorrelated random field is presented.
