Cracked volume specified work of fracture.
Original language description
The paper introduces a method for the determination of fracture mechanics parameters of quasi-brittle materials based on specification of the energy dissipated in the non-linear zone at the macroscopic crack tip (the zone in which the failure mechanismsoccur during the fracture process in these materials) according to the volume of this zone. For an estimation of the size and shape of the zone evolving at the crack tip which is in the case of quasi-brittle materials referred to as the fracture processzone (FPZ) - a special technique is being developed. The procedure is based on a general description of the stress field in cracked bodies carried out byWilliams power series in combination with the philosophy and selected features of classical non-linear fracture models for concrete, i.e. equivalent elastic crack models and cohesive crack models. The estimation of FPZ development during fracture, as well as the analysis of the progress of the energy quantity dissipated there, is illustr
