Originální abstrakt

The paper presents a numerical analysis of fracture processes in testing specimen configurations with substantially different crack tip stress constraint levels. Specimens of several sizes and relative notch lengths are taken into account. The features of the distribution of current/cumulative value of fracture energy along the specimen ligament are discussed and related to estimations of fracture process zone (FPZ) size and shape, in which the energy is dissipated. Significant effect of the stress constraint on the size/shape of the FPZ, and consequently the energy dissipated within it, is reported.
