TY - CONF A1 - Baer, Wolfram T1 - Validation of a low blow specimen technique for R-curve determination using a drop tower N2 - The effect of bouncing strikes on crack extension in low blow tests has been investigated. • Crack propagation sensor signals, force-displacement records and loading level have been analyzed. • Additional crack extension in the specimen due to bouncing strikes of the hammer is not to be expected. It can be seen as a major experimental advantage that the striker does not have to be catched after the low blow test. • This has to be proved for the given conditions of test setup, material and loading.
