摘要：

In this study the split Hopkinson pressure bar technique was used together with high speed photography and digital image correlation to investigate the dynamic tension behavior of Kuru Granite. High speed photography at 200.000 fps was combined with digital image correlation technique to obtain the displacement and strain fields on the surface of Brazilian disc test samples. The advantage of such a high frequency is that strains prior to the dynamic failure can be observed even if the material is brittle. (C) 2014 Published by Elsevier Ltd.
