The properties – e.g. effective fracture toughness and effective crack length, fracture energy and also modulus of elasticity – are calculated on the base of load-deflection (l-d) diagrams from mentioned test. An approximation of model of recorded l-d diagram is possible to use for estimation of these properties, which can serve as input values for numerical modelling of fracture. The model – bending fracture model – of l-d diagrams obtained from experiments is introduced in this paper.
