Originální abstrakt

Values of fracture parameters of quasi-brittle building materials are usually determined from results of tests per-formed on notched testing specimens. The contribution deals with the influence of various shapes of tips of notches prepared by a diamond saw in three point bending (3PB) specimens. The influence of the notch tip shape on the applied force corresponding to a failure initiation at the notch tip and also on the critical applied force ap-propriate to the maximal load-bearing capacity of the specimen is studied. Calculations are performed in two fi-nite element method (FEM) systems (ATENA, ANSYS) based on two different approaches to fracture descrip-tion (Cohesive crack models and LEFM, respectively). The numerical results obtained by both FEM systems are compared. The influence of notch shapes and width is quantified.
