Basic features of aggregate-matrix-interface fracture of concrete: pilot modelling.
Original language description
In this paper, the attention is paid to investigation of the importance of the interfacial transition zone (ITZ) in concrete for the global fracture behaviour. A simplified cracked geometry (con-sisting matrix, ITZ and aggregate) is modelled by means of the finite element method with a crack terminating at the matrix–ITZ interface. Numerical studies assuming two various ITZ thicknesses and several various ITZ elastic moduli are performed. Based on the values of the opening stress ahead of the crack tip (its average value and stress range) a few conclusions are discussed. The pilot analyses dealing with the effect of ITZ on the stress distribution should contribute to better description of toughening mechanisms in silicate-based composites.
