Determination of the Dynamic Stress Intensity Factor for the Four-Point Bend Impact Test
by Rokach, Ihor V.; Łabędzki, Paweł
A simple method for determination of the dynamic stress intensity factor (DSIF) variation with time during a four-point impact bend test has been proposed. A formula for DSIF calculation from the recorded loading has been obtained using modal superposition method. Results of calculations for different specimens have been compared with the experimental data and the results of the direct finite element analysis.
