Concrete is represented as a two-phase material in this paper. Behaviour of a crack with its tip on the interface between two different materials - hardened cement paste (matrix) and aggregate (particle) - is modelled. Input variables of the model are considered as random variables using LHS method/FREET software. Then results of statistical/sensitivity analyses of output variable - the critical stress for the intersection of coarse aggregate particle - are presented.
