Dynamic effects in the impact testing of brittle materials
The results of an experimental investigation of impact failure in a glass, a glass-ceramic and two conventional ceramics are reported. This revealed the occurrence of complex dynamic effects during impact as a result of vibrations induced in the test specimen. These effects were studied by using strain gauges fitted to the impacter and the specimen. To aid understanding of the observations, computer simulation of impact behaviour was undertaken and the results were compared with the experimental data. Conclusions are drawn concerning the design and limitations of impact testing machines of the pendulum type for investigating impact failure of brittle materials. The value of instrumentation of the pendulum and of computer calculations of the type described in this paper is emphasized.
