The aim of the paper consists in the comparison of two experimental methods which are used for the study of the ceramics fracture under dynamic loading. The experimental study has been performed for the specimen of the Al2O3. The loading has been performed using of the Taylor test. The impact velocity when the fracture of the specimen starts has been determined. Using of the numerical simulation of the given test, the dynamic strength of the given material has been evaluated. In the next step, the dynamic Brazilian tests has been performed with a Hopkinson bar, at strain rates 76 s-1. The numeric simulation showed the agreement between results of both methods.
