Fracture behavior of a crack in a matrix/aggregate (MTX/AGG) system is studied. Influence of the Interfacial Transition Zone (ITZ) between the individual phases on the fracture response is investigated. It is discussed how the crack propagation process depends on properties of matrix and aggregate but especially the influence of the ITZ (that arises between the individual layers) is investigated. Various combinations of materials of matrix, aggregate and ITZ affect the fracture behavior of the whole system. Numerical simulations of a crack terminating at the MTX/ITZ interface based on the finite element method are presented to analyze the critical loading and discuss the effects of several parameters (ITZ thickness, AGG radius, MTX/ITZ elastic mismatch) on the crack propagation near a bi-material interface.
