Abstract

In order to measure material properties under conditions of metal cutting, wire drawing and missile penetration, a biaxial shear experiment has been performed at very large strains (approximately 4) and at a very high strain rate (0.4 x 1.0 E5/s) using a special specimen with a thin (0.25 mm) ring-shaped gauge part. The loading device is a tension-torsion Hopkinson bar apparatus, which can also be used at low and medium strain rates. A special electro-optical technique has been developed for the direct measurement of the axial and angular displacements and the shear stresses on the specimen. Equivalent stress strain curves from shear tests of AISI 316 have been compared with tension curves.
