Eugeniusz Ranatowski, Ryszard Strzelecki, Jan Sadowski
The problem of proper interpretation of impact bend test diagrams for an accurate evaluation of cracking parameters of tested materials seems to be very important. The paper presents possibilities of the use of mathematical methods for processing fast dynamic phenomena in an impact bend test. Established are exemplary algorithms of diagram processing within mathematical filtration based on averaging the random variable an oscillation within the scope of time and frequency. A procedure for determination of characteristic points of the sample impact cracking process has also been provided using an example of specific processing F-t diagram for Charpy V sample of 18G2A steel.
