ABSTRACT
In the development and analysis of ceramic materials for impact-related applications, an experimental investigation of their dynamic behaviour at high strain rates is highly important. The present study discusses the dynamic behaviour of alumina (Al2O3) at three different strain rates: 101.96 s–1, 136.96 s–1 and 243.78 s–1. The effectiveness of the pulse shaper in terms of its ability to achieve constant strain rate and dynamic equilibrium during the test is also investigated. A parameter called peak strain rate to average strain rate ratio is used to measure the effectiveness of the pulse shaper to achieve a constant strain rate. The stress-strain response of the alumina is also explored in this study.
