Abstract

In this paper, the dynamic tensile properties of brittle materials were studied by using the dynamic Brazilian tests. Combined with a high-speed photographic system, a split Hopkinson pressure bar (SHPB) was used to conduct dynamic Brazilian tests on three brittle materials: Al₂O₃ ceramic, granite and poly(methyl methacrylate). Based on the images recorded by a high-speed camera, the displacement and strain fields were obtained by the digital image correlation method. The dynamic deformation and failure of the brittle materials were analysed. The rate-related dynamic tensile strength of the three brittle materials was also determined and analysed. The results show that the dynamic Brazilian test is an effective method to study the dynamic tensile properties of brittle materials.
