New applications of the Hopkinson pressure bar technique to determining dynamic bahaviour of materials

Experimental results of dynamic uniaxial compression, tension and shearing tests on brittle and metals at high strain rates are presented. In these dynamic investigations a standard Hopkinson bar device with a pneumatic launcher was used. Various testing configurations and accessories of the set-up are shown here. It makes possible to determine dynamic behaviour of materials in different modes of an examination having the above test stand only.
