Original Abstract

Concrete is represented as a two phase material. 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 and FREET software. Then results of statistical, sensitivity analyses of output variable, the critical stress for the intersection of coarse aggregate particle are presented.
