INFLUENCE OF NOTCH SHAPE AND WIDTH ON LOADDEFLECTION DIAGRAM/FRACTURE PARAMETERS OF CEMENT BASED COMPOSITE
Řoutil L., Veselý V.
pages 200 - +11p., full text

Values of fracture parameters of quasi-brittle building materials are usually determined from results of tests performed on notched testing specimens. The paper focuses on the influence of the notch width and the notch tip shape on the quasi-brittle behavior of the specimen during the fracture test. The influence is investigated via numerical simulations of the three-point bending tests of notched beams and its significance is expressed through values of fracture parameters calculated from the simulated testing records. Also the influence of FE mesh arrangement is monitored.
