Název v původním jazyce

Interplay of probabilistic and deterministic internal lengths in simulations of concrete fracture

Popis výsledku v původním jazyce

The contribution presents simulations of fracture in concrete beams loaded in three-point bending via disrete model. The size and distribution of discrete units reflect the concrete heterogeneity and together with properties of their contacts provide an internal length scale. Due to a random placement of the discrete units, the model mimics natural randomness of material structure arising from its random heterogeneity. A second random component of the model considered is additional fluctuation of material parameters at contacts between the units. This randomness reflects variations in material properties due to mixing, drying, etc. and it is considered in a form of autocorrelation length.
