Abstract
In this work, results of a numerical parametric analysis are presented in order to compare them with experimentally observed concrete cone failure features. Such a kind of failure is typical for cast-in steel anchors embedded in concrete substrates. Thus, numerical simulations via finite element method have been performed in order to investigate basic fracture parameters for specimens with a short fatigue crack and stress distribution for specimens without any crack. Several parameters were varied and their effect on the stress intensity factors or distribution of stress tensor components around the anchor corner were studied and discussed. Slight differences between the average angle typical for concrete cone failure observed experimentally and numerical results were found out and thus, more complex numerical simulations shall be recommended.
